It would be just great if you would make Aya's Voices and Leyla's Animations ( walking, climbing, etc ) and animations the standard for each female skin. That would at least weigh out the extreme masculine grunts of Bayek. It's maybe not the worst thing to have, but in terms of immersion and variety it would be quite essential.
I personally don't care about the cutscenes, but to have the full Aya-Experience in the rest of the game would actually be enough, regarding the equation of time and energy needed to implement these little adjustments for the developers who'd make the update.
I just don't know enough about proprgamming to know how time-expensive such a tiny arrangement woudl be, so i just ask for it anyway.

Another thing i would ask for is the possibility to change outfits on skins - at least to the extend, that if you play Aya, Tahira, Leyla, etc, you can change between their outfits with each of that skins, while having the generic voiceover and animations for game-situations.
I don't know if it's too much to ask for a little update, but i always wished, in terms of gender and having access to a female character, that Origin would have been like Odyssey in that regards. It feels so strange to finally have the model of Aya - but nothing else x). Almost cynical.
Maybe you could arrange that ?
