Sure, but Age of Empires only has three African factions (Mali, Berbers, Ethiopian), whereas we have 4 human factions and 8-10-12 non human factions (depending on how you count them).
Our Vodoo Vampire army was made to be the one inspired by the Dahomey / Yoruba and « vodoo culture », so that's where the Gbeto should go, it's their « true house ».
Also, I think the brutal, bloody short range / raw strength fits that army more
Speaking of Ethiopia though. I finally saw a photo of a Shotel Blade. YIKES! What kind of sick f@#k came up with that monster!? "Ah yes, let's make a sword that both parries... and removes internal organs when it does so."
