[DC] If the Joker was female , do you think there would be any type of romantic relationship between her and Batman? Would it be similar to the love/hate relationship Bruce has with Catwoman?

The main reason Catwoman and Batman are able to have a relationship that is more flirtatious than adversarial is a simple one - she doesn't kill people. For Bruce, being a demented serial killer is an absolute dealbreaker.

That said, the Joker's obsession with Batman is often presented as having romantic or sexual overtones; there's no reason why that would go away if he was a woman. So there would probably be plenty of flirtation on the Joker's end, but none coming from Batman.
