I guess the only question I could ask is why wouldn't you? You've clearly put a lot of thought and research into it, it's at least partially supported by extant lore, it believable, it's unique, and it's really interesting. Perhaps a bullet point here or there might need to be retconned as the developers release more official lore about Ala Mhigo, but I don't foresee anything invalidating your character's development in this direction. I like it a lot. Freakin' do it.
