"I have another Joker story, but it’s kind of an out-of-continuity one. I feel like I’ve said so much with the character at this point. And I really love that character. Like I said, I’m doing one more, but I’m looking to do it out-of-continuity. So no, he’s not coming back to fight Gordon. But you might get a glimpse of his future in a later issue somewhere."
A Joker story that takes place outside of the current coninuity could definitely be interesting and refreshing, and may even be prefered by some fans.
