hello Dleufer and Michi,
I agree with Duga, it's probably not related.
You can find a Fèfö from Kouroussa on my youtube account (danielkonate). By the way, I only know one Fèfö version - it's the same in Kouroussa, Sangbarala, Baro and Babila/Fadama/Fissadou at least.
Another rythm that can be played is Tasaba.
Fakoly is a rythm for the Kourouma clan and also for féticheurs (there are lots of Kourouma féticheurs). It's been played on Tyèuru/Kèuru drums before, not on dunduns. Today it can be played instead of Koma for the Koma mask (I think these two rythms were one Kèuru rythm before).
Billy has put it on his last disc as a binary rythm. Maybe he has heard it once that way, but I think he changed it with the mates in CKY, because it is so close to a binary rythm - I only heard it as a ternary one during fêtes, but once in class they showed it as binary (than it's close to Nkokè/kassa II). A friend of mine has got a recording of it in the binary style, but that was during a concert like fête and they were fooling around a bit, so I still don't know if this binary version exists in Hamana/Gberedu traditionally.
BUT: Tasaba can be played for the mask (1), for the girls (2: Fèfö) and for féticheurs (Soro fête), so this could be a little relation. but I'm not convinced.
Fakoly manyi! Kunatè kanyi! d;-)
