Hear me out, hear me out! Hazbin Hotel AU where Adam and Eve are in hell, they're trying to be parents to humanity and they're the ones trying to get souls into Heaven. they were once close with Lilith and Lucifer but after they gave up on the exterminations they had a falling out. Charlie stops by to help instead of Alastor (and actually uses her powers). Shes accompanied by her guard Vaggie and Angel who she has posing as an assistant so he can bring back money to Val doesn't have to be on the strips. Their first occupant is their son Cain and Abel is the one in charge of the extermination.
This is in no way coming soon I have a lot on my plate, but it is something I'm tinkering with. It sounds fun.
