Localization for regions (French - Africa)

Hello everyone,

I got a question regarding the Localization.

My client would like to get a locale for French - Africa and one for French - Europe.
He would like to customize the content and promote some products in both areas.
I haven’t found any locales in the list that could fit for Africa.
For Europe, I think I could just use the French (Standard).

Any ideas ?
Thanks for your help !
