Bertinelli didn't suffer from that. Initially she existed separately from the Bat Fam but during the 90's when the Bat Family expanded with multiple titles, they managed to fold her into their world. Her first appearance in the 80's are very different from her appearances in Cry for Blood and Simone's BOP.
I think bringing in Helena Kosmastos and developing her would be more ideal. Or at least reveal that she had more than one daughter.
