If I was thinking of a girlfriend he had that was more like a female Bruce I'd say it was Barbara.
Absolutely. I always found that scene hilarious in Nightwing-Huntress, where Babs is telling Dick "I get that she reminds you of -- I get that she feels familiar," like Dick sleeping with Hel was some Oedipal thing... when Helena is pretty much nothing like Bruce and Babs is a few smiles a year shy of his clone.
