I'll sign up for this. Anyways I'm just going to formally post here that if you are going to do this I would suggest a role for this. Your call on if you include it or not but based on the whole item thing I think it would be cool
thief - evil neutral (confirmed in role list, just cut a citizen)
abilities: can steal an item from a player during the night or use any item he stole. Stolen items can only be used once (optional).
win condition: survive to see the town lose
