So the bijuu are formed from her cast off chakra and the rest of her is trapped in the moon. Could she be reintegrated into the natural cycle bit by bit via a VERY (very very very etc) careful chakra drain, and once the moon is just a moon and all of her chakra is back in the world, reborn as an untwisted, balanced version of herself?
Pros: cute bunny demon thing goes through the evil baby orphanage transformation, corrects chakra imbalance shark that kishimoto jumped, fun premise for exploring more mythology slanted things in setting
Cons: evil bunny moon goddess is still a dumb fucking BBEG,what to do about Zetsu (just have him break up in the reincarnation cycle and get resistributed maybe?), that's about it
