You know, I was thinking the whole 'werefrankenpire' thing might have some potential on it's own. Imagine a movie where a mad scientist builds a monster out of body parts and animates it. Then the monster is bitten by first a werewolf and then a vampire. So now he's a monster by day, a vampire by night, and a wolf when the moon is full. In order to kill this thing, you have to shoot it with a silver bullet, drive a stake through it's heart, then burn it -- but if you don't do those three things in the right order, then you only piss him off!
