some suggestions from UP, UB, UHV in relation to civ Brasil:
UP: The power of "Bossa Nova"
the first time it moves the capital to a non-coastal city generates a golden age.
+ 1 / + 0.5 happiness in all cities by cultural level.
(Bossa Nova is a more elite variation of samba, from Bossa Nova there are songs like "Garota de Ipanema" or "Chega de saudade" that are a symbol of Brazilian culture in the world, during the time when these songs were composed occurred the construction of Brasilia and Brazil underwent strong economic development, notably because of the automobile industry, which was then called the "Anos Dourados", which is why the idea of the golden age.
The part of UP's happiness is due to the Bossa Nova music being a reason of great national pride in Brazil, and this added to the people of Brazil being known for their happiness, I think it would be appropriate to reward the production of culture with happiness. Within the gameplay mechanics normally cities in Brazil reach level 3 or 4 of culture, they hardly reach 5 or 6, so the amount of happiness generated would not be unreasonably large)

UHV1: The coffee cycle - Get at least 500 gold by selling coffee by 1830/1850/1880, get at least 2500 gold by selling coffee and rubber by 1880/1920, Build Ironworks by 1930.
(The first UHV is based on the fact that Brazil has been the largest coffee producer for the last 150 years, so a fact of this historical importance would deserve a UHV, coffee cultivation and especially its export were very important during the second reign (great share of exportations of brazil) and the beginning of the first republic (coffee with milk policy), there were two booms in coffee export from brazil, the first between 1830-1850 (but for gameplay mechanics it is very early since brazil spawn in 1822) the second occurred between 1880-1930.
Parallel to the coffee cycle occurred the 1879-1912 rubber cycle, the use of gold obtained from the sale of rubber would also be a way to encourage the player to colonize the Amazon, in addition to the end of these two economic cycles added to the great depression of 1929, generated industrialism by replacing imports from Getúlio Vargas, which is the third part of the UHV, to build Ironworks to represent the consolidation of the base industry in Brazil with the inauguration of "CSN - Companhia Siderúrgica Nacinal", which was a great steelworks for steel production obtained by Getúlio Vargas through financing provided by the USA for the entry of Brazil in WW2.)

UHV2: The "Golden Years" - Move the capital to Brasília and connect it by highway to at least 5/6/7 cities until 1950/1960.
(This UHV would serve to portray the construction of the capital Brasília and the importance of the automotive industry for Brazil, IMO these facts are historically very relevant for Brazil and would be a very different UHV, since no other in the MOD that asks for a change of of capital.
"Os Anos Dourados" is the way in which part of the 50s is known, where mainly under the government of Juscelino Kubitschek, Brazil builds the capital and important highways to connect various parts of the country, with the new capital as the center)

UHV3: Brazil of great works (Maracanã, Itaipu, Cristo Redentor, trans-amazônica) - Build the wonders Wembley, Hoover Dam and Cristo Redentor, and a highway that connects the most extreme tile from east to west of Brazil until 1972.
(This is based on the UHV that is already in the MOD, which is the construction of the wonders that are well known in Brazil: Maracanã, Itaipu and Cristo redentor, I also added the "trans-amazonian" highway which is one of the "pharaonic works "that occurred during the military dictatorship of 1964, together with the construction of the Rio-Niterói bridge and the Itaipu hydroelectric plant, this highway is the third largest in Brazil and connects the Brazilian Northeast to the Amazon (look at the map in this link below), in the game build highways is very simple and cheap so I don’t know if it’s going to be good to add, or if you just leave the wonders.)

UB - Sambódromo / Carnaval de Rua - replaces arena, in addition to the normal effects, generates + 1 / + 0.5 culture and + 1 / + 0.5 gold for the cultural level of the city (this adjustment by cultural level is interesting because it generates a natural balance of the bonus since it increases with time, and as cities in Brazil rarely reach level 5 of culture, for the most part the game would generate 2, 3 or 4 of culture and gold per city, which is not so exaggerated, if it is, you can put only +0.5 per level or put a fixed bonus of + X culture / gold. As Carnival has existed in Brazil since the 16th century known as "Entrudo" and from the 19th century in the most contemporary way, the UB sambódromo could be available from the spawn)

I believe that these changes will make the gameplay with CIV brasil more focused on the production of culture, building wonders related to Brazil, negotiating diplomatic agreements for the sale of resources or the purchase of technologies, moving the capital from Rio de Janeiro to Brasilia, construction of highways and colonization of the Amazon in search of rubber or area for new cities. These actions are, IMO much more connected with what would be expected from the game with Brazil, concentrating the actions on a more constructive / peaceful game and less on military conquests / Brazil-WestCanada strategy (from previous games I had to capture cities in Africa to try getting slaves, after I bought the ones from the Congo and they didn't produce anymore, or else having to found cities in other regions / capture Buenos Aires to get the required number of pastures. This type of action doesn't make much sense looking at the history of Brazil.
That other UHV Pindorama, I think it would be better if replaced by another one, since as the new map will have a much larger area it will be very simple to get 20/25/30 jungle tiles and use the workers to build the reserve forests, and that could still generate the situation of building the capital and national park in the amazon and having a city with 20 free specialists, which would be something very strange. on the old map too but on a smaller scale.
Regarding the dates of the UHVs and the values of the bonuses, we have to discuss to make an appropriate balance, if you want to comment feel free.
