Like, all of the unique GG could be their own leaders. My personal vote would be for Jose Antonio Paez, the Centaur of the Plains.
I would rather have a more diplomatic or culture centred leader for Gran Colombia than another military one such as José Antonio Páez. He also actively worked against Gran Colombia, plotting its separation, so I guess it would be odd to have a leader that wanted to separate the country it will be leading in-game.
I would go for Antonio Nariño (currently a Comandante General in-game), Francisco de Miranda or even Francisco de Paula Santander (also a Comandante General). This could be the abilites for these leader options for Gran Colombia.
Antonio Nariño (vice-president of Gran Colombia and president of Cundinamarca) could be a more cultured centred leader, as he brought many ideas from the Enlightenment to the colonies, such as translating the Declaration of the Rights of Man and of the Citizen to Spanish (he was sent to jail by the Spanish for doing this). He also became rich from importing products from the Old World.
Leader ability name: "
Patria Boba or
United Provinces of New Granada": receives a culture points bonus towards civics that have already been discovered by other civilizations, you get some gold yields from cultural buildings. (during his political career some defended a Federal system, such as the one in the US and others a centralist system, such as the one in France, both were tested during the independence movement)
Leader agenda name: "
The Precursor of Liberty": dislikes civilizations with fewer civics as himself, likes civilizations with more civics as himself (He was inspired by the heroes of the American Revolution, such as Benjamin Franklin)
Capital city:
Bogotá or
Villa de Leyva
Francisco de Miranda (briefly dictator of Venezuela) could be a more diplomatic centred leader, as he established contact with countries such as the UK, France and Russia to seek support for independence. He also fought in the American Revolution and in the French Revolution.
Leader ability name: "
First Republic of Venezuela": receives more diplomatic favour points from each alliance he has with other civilizations and/or when fighting a war together with other civilizations
Leader agenda name: "
The Precursor of Independence": dislikes civilizations who have conquered other nations capitals, likes civilizations which have conquered none or less capitals from other civilizations.
Capital city:
Caracas
Francisco de Paula Santander (vice-president and acting-president of Gran Colombia when Bolívar was off fighting elsewhere) could be more centred on culture, as he favoured the rule of law and constitutional rule of the country, as opposed to Bolívar's almost dictatorial rule. He drafted much of the early laws and constitutions of Colombia and founded various cultural institutions, such as public schools, the National University of Colombia, the National Museum of Colombia (the first national museum in both North and South America) and much more.
Leader ability name: "
Constitution of 1821": cultural buildings from conquered and/or recaptured ("liberated") cities receive no damage. Military buildings produce some culture and/or can produce cultural buildings faster. (Considered the first constitution of Colombia/Gran Colombia, laid the legal framework for future constitutions and for the rebuilding of the country after the war of independence)
Leader agenda name: "
El Hombre de las Leyes or
The Man of the Law": dislikes civilizations with low diplomatic favour points production, likes civilizations that produce a lot of diplomatic favour points
Capital city:
Bogotá or
Cúcuta
