Can I use Francesca Prelati as a master?

The idea of another Master somehow related to Albert or the Prelatis is interesting but I'm not quite sure how you'd make it work. Like vance said, playing the actual F. Prelati would invite all sorts of body-snatching weirdness, and Albert would probably just try to kill him/her on sight by siccing Berserker on them. That's one teammate down right off the bat. Another descendant wouldn't work either unless you're content with them not being the heir or them being from a branch family, because only the Edelfelts can have two heirs.
