Expand the conflict a little and mirror original British concerns about Boers claiming their own port by having Afrikaner militias attempt to seize southern Mozambique from Portugal, maybe.
I wouldn't break things up TOO much.
Remember, your nations have to have:
1.) sufficient population
2.) sufficient revenue
Without either of these things, you start to run into problems... like how the nation doesn't simply implode.
If you make it past that small stumbling block, you still have to finance the military of your nation- an equally weighty problem.
With the African nation-states, you have a MAJOR issue... Africa is not a very 'rich' continent.
There are some very large resource deposits in (modern day) South Africa, largely in the area of the old Boer Republics. Then, along the West Coast and in the Lakes area you have some diamond deposits, along with some scattered coal seams. The North Coast and the 'Curve' have some significant oil deposits- but these are largely unexploited at this time and much is located offshore, especially in the 'Curve.' The only remaining resource is the scattering of Sahara uranium, which is neither of use nor even of interest at this time.
The vast majority of the economies of Africa are based on herding and subsistence farming... with Egypt and South Africa having some small manufacturing capabilities at this time. Few areas will be able to support a large standing force; indeed, a 'large' African military might be about the size of a single State in the Confederacy, and the 'average' military might be no more powerful than Arixo or the Navajo or Lakota nations!!! We are talking a few thousand troops and maybe 4 - 5 dozen aircraft in the entire government-controlled military forces
. Some North American and European mercenary groups will likely be as powerful, and certainly entities like Blake Aviation Security will have as much (if not more) manpower and equipment.
Even in the overly-optimistic world of Crimson Skies (where money seems to appear out of this air) only about 6 nations in Africa would be able to field anything larger than a glorified pirate gang: a united
Boer Republic, British South Africa, Egypt, Italian Ethiopia, French West Africa, and the Dutch Congo. Of all
of these, only Egypt and a Boer Republic would really fielding their own military
in the sense that some colonial power would not be funding it... but they would still be relying on a foreign arms supplier for any major equipment (aircraft, tanks, ships, sundry military vehicles).
So let's not get too happy with redrawing the map- Africa is humanity's cradle... but the problem with cradles is that they are generally pretty confining.
Not wanting to rain on your parade, man... I ran into the same problem in the Caribbean, and an additional issue as well- some islands were not big enough to support aviation facilities
!!! This caused me to have to totally delete my original attempt and restart a year or so ago with a book that focused completely on Cuba rather than trying to cover a bunch of postage stamps with a few thousand people and no place to put an airstrip!
