But you're making more work for yourself than you need to. I don't know why people are dismissing Barbara as if her being Batgirl hasn't been an integral part of the Bat mythology or that she isn't the most well known version of the character. Vast majority of people knows Batgirl is Commission Gordon's daughter and that she has red hair. You only have to look at something as recent as DC Superhero Girls to see Barbara is the one that is still associated with Batgirl. Barbara, along with Dick Grayson, are the two most iconic members of the Bat family. Cain and Brown are not. There's no logic in making Batgirl anyone other than the most well known version from a marketing perspective.
