Well, Buddhism is a religion. Instead of Gods, they have Buddhas. So like Gods, they have a "system" of which they are important parts. Like the Biblical God was to his "Heaven System".

I believe Ajuka could make the Evil Pieces able to reincarnate Gods/Buddhas, but he can't overwrite the "systems" of the different religions. Either because it would be dangerous to do so, or because despite his expertise in equations and calculations, he can't find a way to overwrite the "system."
