The "pulling one of each suits" bit sounds really promising! It could work really well with scenes necessarily composed by four factors, like the ones you mentioned!!
We immediately thought about how it could be used to create a "Clue"-like game, in which a serial killer is on the loose and each day you'd pull one of each suits to determine their Method, Weapon, Location and Victim...
Crap, now I guess we're making this game.... Is it okay to use the suits idea and give you credits for it?!
