So, I complied a list of the most populated West African groups. These are the most populated 15 to 16 and my concept is to group West Africa in sensible cultural clusters that can be used to unite West Africa eventually into sensible divisions. See as follows:

People.........................Language (or Language group)
1) Yoruba people.........................Yoruba
2) Hausa people.........................Hausa
3) Igbo people.........................Igbo
4) Mande people.........................Mandinka/Bambara
5) Akan people.........................Ashanti Twi
6) Fulani People.........................Fufulde
7) Ijaw people.........................An Ijaw Language
8 )Ibibio people.........................Ibibio
9) Kanuri people.........................Kanuri
10) Gbagyi people.........................Gbagyi
11) Wolof people.........................Wolof

12) Tiv people.........................Tiv
13) Ewe people.........................Ewe
14) Mossi people.........................Mossi
15) Songhai people.........................Songhai

16) Fon people.........................Fon


The top 15 groups can be further culturally divided as follows:

Coastal:.........................Yoruba-------Akan-------Ewe
Riverine:.........................Igbo-------Ibibio-------Ijaw
Midwest Sahelian:.........................Hausa-------Kanuri-------Songhai
Western Sahelian:.........................Mande-------Fulani-------Wolof
Inland/Interior:.........................Gbagyi-------Tiv-------Mossi

The capital cities of these regions could easily be as follows:

Coastal:.........................Eko (Lagos)-------Abidjan-------Accra-------Monrovia-------Freetown
Riverine:.........................Enugu-------Calabar-------Port Harcourt-------Onitsa-------Aba/Idah
Midwestern Sahelian:.........................Kano-------Maiduguri-------Niamey-------Sokoto-------Zaria/Daura
Western Sahelian:.........................Dakar-------Conakry-------Bamako-------Nouakchott-------Timbuktu/Mopti
Inland/Interior:.........................Abuja-------Kaduna-------Jos-------Ougadogou-------Minna/Makurdi


My end vision is for Western Africa to become one seamless country, like the United Sates. If Cameroon could join the Riverine and Chad could join the Midwestern Sahelian, that could be culturally workable too.
Each of these regions could even serve as their own sub-governmental level; e.g. a governmental level somewhere between a country(West Africa) and a lower level, like a state.
I think this will be ultimately more satisfying for West Africa. Thoughts ? ? ? ? ? ? ? ? ?

Heh

Lol.

Good attempt but ultimately people will have to democratically decide where they want to belong. And how the want to co-exist.

Via a plebiscite.

A new complex re-organisation cutting across countries and official French/English/ Spanish language areas would be difficult.

Aside South West Nigeria, division along religious lines would even be better. Since religion will remain a divisive matter until the end of the world.

An African super-State where each tribal group above 250k people or any figure to be agreed on will have 80% autonomy would work better. A loose confederation of African people.
