Complete voiceover for the whole game when playing as a female character in Animus control panel would be an awesome thing I will love that. But at least when skilling and moving around the world as Aya or whoever female character would make significant change for the good.
It might not happen but if Ubisoft makes brand new DLC for Origins which gives us Aya story while Bayek main game one is running I will be loving it and spend money for it instantly. Just multiple main quests, few outfits for Aya and some new weapons plus ofc all side quests fully doable as Aya even in the main game and some more what they can do..
Becouse I really like Egypt in AC Origins and Aya is one of my most favorite character of the Franchise maybe even over Kassandra (R.I.P.Ezio you are the best men protagonist). That easily could be the very moment when the dream comes true.
