I never really saw Bruce/Helena in a daughter relationship light and for the same reasons that icon-uk pointed out, Helena doesn't have many similar characteristics to Bruce. I see them as mainly two different vigilantes who don't work well when together but they truly shine when they in their own books (Bruce and Helena). As for Dick and Helena, Dick is, like Bruce, about confidence, calmness,integrity and self control and has the finer qualities of both Superman and Batman and grew up in the superhero community learning a lot from those around him, Helena had neither, she didn't good role models, she lacks experience compared to Dick in tights, she is more about losing control and most of the time stubborn, loud and highly opinionated until someone boinks her on the head (of course I'm speaking of pre-BOP Helena). Now if you try to work a relationship from that angle than you have something there.
