I'm interested! Though I may not have time to join, I'm not too sure at the moment.

As for the issue of who lives and who dies, couldn't you assign a number to each character and randomly draw who dies each week? They could then talk it out, come up with the clues, etc.

And there could be just a nonsense "afterlife hangout" where they all angst about being dead and killing each other, I dunno.
