Reverse sheriff is better than fully insane sheriff, but consider making each one unique if there is a sheriff/hunter>sheriff occurance so one may be sane and the other insane.
Removing jester would be good.
Ive wanted to use an insane sheriff who didnt know he was evil for some time but having it go from town to anti town is imba. Especially when the game is already doing that.
Hunter>some sheriff means it loses a town, gets a weaker night action, and needs 2 nights to figure itself out. Thats plenty a nerf imo. No need for it to change alignment
