In the World of Superheroes -- Could You See the Kindredness of Batgirl and Supergirl?

Batgirl was not mature enough to be a Batwoman, but, she was mature enough to fill out her Batgirl suit and help the Dynamic Duo: Batman and Robin, if need be; on the television program, "Batman".

It is ironical, that the characters of Batwoman or Superwoman, never were created (from what I understand). Supergirl (however), could be Batgirl's kindred (superhero suit-filling) cousin, in the world of superheroes. Would you not say?
