Your train of thought was a lot better than mine. As soon as I started pondering the idea, my mind defaulted to the vampire hilarity of the moment, which is Twilight. haha Naruto can be the werewolf.

My default is that any pairing with Duo in it is a pairing I'll read. (This mysteriously includes DuoxRelena) XD; So don't mind me. haha
I totally wasn't expecting you to do all three, though in no universe will I object to 1x5 and Aeris/Tifa should you choose to accept your mission. ; )
