The Syndicate

Yo, so I'm currently stuck in a bus station and I haven't slept in ~27 hours, but I just had an idea. Excuse my terrible spelling and grammar tho, this is a cellphone post as well.

Has anyone ever played a game of double elimination mafia game? How it would work (in my head anyways) would be people would all start in a normal mafia game, but if they died they'd continue playing in a zombie game. The twist would be zombies have different alignments than their alive self rather than their zombie self. So a player could be mafia but then civvie as a zombie. The game would end when the win conditions was fulfilled in the alive game? Maybe two people are Lynched a day in the alive phase, but one zombie is rezzed and one zombie is perma-out when they are lynched in zombie land? Rezzed zombies keep their new alignment?

Thoughts? Does any of this make sense? Does this game type already exist?
