Avatar bleach crossover

I’m working on an idea with an avatar bleach crossover if anyone familiar with the anime it’s about a boy who becomes a soul reaper which is a type of spirit guardian that protect the living and the dead from demonic dammed souls called hollows which are souls that have not moved on and become obsessed with staying in the human world that causes their souls to rot and corrode the turning them in the monsters inside and soul reapers have to be anguish them if they can get them on time ( which means sending them into the afterlife)
Now in our story the hollows start showing up on Pandora while most are human soldiers the leader is hiding in a Navi body 
Their motives on Pandora is a mystery so the soul reaper send their best agents to look into it which are Joan of arc and Teddy Roosevelt who became soul reapers after they died the story focuses on Jake and neytri adopted kids spider and kiri come across a rda soldier who turns out to be a hollow who is using a humans disguise chases after them the. When Jake and neytri try fighting the posed human he shows his tru self in a fight we’re he nearly kills the sully if not for the intervention of Jonah arc who wounds the monster but ends up losing du to her fire phobia causing the hollow to take advantage of her moment of weakness forcing spider to wiled her sword showing his latent potential as a spirit warrior allow g him to kill the hollow allowing Joan of arc to take spider and Kiri under teaching due to her strong connection with eywa kiri can force hollows to show their true forms or as I like to call it popping them
