Batman has a pretty big rogues gallery and has a whole family of supporting heroes in his Batman Family.

Should some minor super villains be spun off to other members of the Bat-Family, in hopes of becoming major villains for these heroes? Dr. Death became a Batgirl villain in 2003 and seemed to work well, despite being Batman's first villain, his focus on poisons and plagues may seem redundant next to the Joker, but in Batgirl he can a big fish in a small pound. If you agree with this premise, which villains should be spun out to which Bat-Family member?
