My list, in order:
Ashanti – Y'all know they're my favorites. If you don't know much about them, I'd be happy to make an effort post, but I thought I'd give a preliminary vision of them instead-
My ideas for the Ashanti revolve around the Golden Stool ( see-
http://en.wikipedia.org/wiki/War_of_the_Golden_Stool ) - I think perhaps incorporated as something like a UA with: “The first work of art created by an Ashanti Great Artist will always be The Golden Stool, which grants an additional (dope bonuses) and provides X production for the city that possesses it.
With a UU Akan/Talking Drummer that buffs the combat ability of units and/or the production of cities in its radius, I can imagine the Ashanti shifting the Golden Stool around in conjunction with a Talking Drummer in order to greatly boost the production of a particular city.
The Golden Stool would have the obvious negative side effect of being a super juicy great work that everyone else in the world is gonna want to take away from them, but as long as it is possessed by the Ashanti will give them great benefits. I just don’t have a good idea for what the values should be yet
Vietnam – I imagine them with strong combat defense and a significant passive bonus to defensive culture, although that feels rather unimaginative. I definitely feel those who are concerned about what an Americo-centric depiction of Vietnam would look like, but the nation’s history is so rich that I have faith in a more robust representation. Trung Trac is completely baller and I gotta be honest, I’d even be cool with both twins serving as co-leaders.
Nubia – I feel like they should be paired up with Egypt in some manner akin to how Assyria and Babylon are. I’m spitballing this, but perhaps something like “Wonders built by you and your allies contribute significantly to your Golden Age meter”. There are probably more interesting ways to interpret their syncretism, the problem comes from significantly differentiating them, which funny enough was/is a problem in reality.
Argentina – If you haven’t checked out Leugi’s “Patria Grande” custom civs, check it out right now:

I dig his latest conception of Argentina and I think Eva Peron and the legacy of Peronism is just too fascinating not to include. I understand the resistance to modern civilizations, but I find Argentina pretty compelling as a nation of immigrants and a producer of great people.
Hungary – It’s time, but seal off Europe after this. For real though, Matthias Corvinus is the kind of leader that drags a less relevant civilization closer to inclusion, so for a nation like Hungary it feels like an easy choice. In terms of the their in-game abilities, I got little of interest, and will defer to those more knowledgeable like AbsintheRed (thanks for the feedback, by the way! I definitely did just forget Phoenicia, which is amazing after all the times Tyrian Purple came up)
Timurids Timur is also that kind of dude, but the Timurids shouldn't be slept on regardless. Their empire also nicely fills up a huge empty spot. I gotta imagine they should be in some ways derivative of the Mongols in order to point to their shared lineage, but they should also have some kind of cultural benefits as well to make clear their differences.
Kongo – I’m starting to cool on Kongo, if just because I see how much their popularity relies on the fact that a lot of people have no idea of any other civilizations on the continent; to that end I don’t see very interesting concepts for them or much beyond “Africa needs more” (which is totally true). Still though, they have some really cool aspects to represent, particularly in terms of cultural syncretism. A UA that turns incoming religious pressure into wealth or gold or something could reflect their turn to Christianity in a cool way, but it seems lacking insofar as it’s difficult for the player to control. Still hating on everyone who suggests Nzinga as the leader.
Khmer – I don’t feel super strongly about this one but I was legit disappointed that Suryavarman II didn’t reappear in Civ V because the Khmer Empire’s handprints are kinda all over this game. I would be interested in people's concepts for carving out a unique position for them given what we have now.
Inuit – I realize some people think they’re ridiculous, but I’ll stick with them, even if they might seem liable to be shoehorned into a gimmicky role (after Venice, they can’t be the
most gimmicky). There’s precedence for mythical leaders, though understandably not much love), but really the main draw is their uniqueness.
