Would random Potential Slayers who were turned into vampires before "Chosen" get the Slayer power boost from Willow's spell?
I don't think so. They're technically dead, so I guess you could say the potential has left their body, since they're actually nothing more than a dead body inhabited by a demon.
But then again, would a Slayer that gets turned into a Vampire keep her Slayer strength? As badass as is may sound, I think a Slayer-Vampire would have normal vampire strength, which is more than enough, actually.
