What about having the eliminated player act as Benny, and ihaunt the other players? Assuming you aren't already playing the Ghost of Benny expansion.
P.S. I realize this is an old thread, but since the game just came out, answering when this was posted would have been pointless speculation.
I made a pitch for something along these lines recently in a private message to the Certifiable Studios dudes. I suggested that there could be a separate neoprene play mat that is a graveyard where dead orphans (players) are laid to rest. But instead of being completely out of the game the dead get a ghost version of their character which is placed in the last location where they bought the farm! The dead then get to do some limited actions using a separate graveyard deck that gives them some options to haunt (#@$* with) the remaining living players, perhaps even getting revenge on the person who killed him, or even possessing them, ala Linda Blair in The Exorcist, or the creepy kid from The Shining (Redrum...Redrum). I thing these abilities should be very limited, but just keeping departed players involved in some manner would be interesting, and fun!
