AHC/PC: Largest Burkina Faso

Let's see if we could get the largest Burkina Faso possible composing of at least all the peoples in the ethnic group that makes up the country.

Maybe also including parts of the northern half of OTL Ghana? I dunno, maybe Thomas Sankara stays in power and gets in a war with the other country while Jerry Rawlings is still in office?
 
Anything involving Sankara seems to be the only way to expand Burkina Faso unless you want to meddle about with the scramble for Africa and internal French Colonial Administrative boundaries in West Africa.
