I know you guys are probably set on an African civil war, but personally I'd be more inclined to having some of historic kingdoms in Africa survive and duke it out. I mean, if this is staying for HOI III perhaps the terrain'll be better and you can up the infra a bit down there. Personally I just think it'd be cool to see Old Mali or Ghana fighting against the Zulus or something...
Anyway, just my two cents.
