Yeahhhh, no, that's too complicated for too short a time. If I do Granny in the sequel game I might think about it, but not for this one.

(She should be able to create other vampires, however, because she's a female vampire--a 'queen' in Parasol Protectorate terms--and the queens are the only vampires that can make more vampires in that universe. But, like I said, if it's that complicated I won't go for it.)
