No, for many reasons
>Bruce would never go behind Dick's back. Not only is Dick a friend, and a partner, but Bruce is like a father to him. It'd be like sleeping with your son's gf.
>Bruce would NEVER do that to Gordon. "Jim, I have secretly been recruiting your daughter to endanger her life to engage in vigilante justice behind your back... Oh also we totally boned. I just rawed your little girl and came in her over and over again with reckless abandon. She got knocked up but don't worry, she got jumped during the whole aforementioned vigilante thing and miscarried, so you don't gotta worry about that. We still cool though, right?"
>the whole thing is Bruce Timm's jerk off fantasy. If he wants to beat off to it, fine, just do it on your own time. Don't make that shit cannon to your well established animated works and force your fetishes on the rest of us.
Bruce is someone with strict moral codes and ideals. He'd never throw those aside to get his dick wet.
