Now
there's food for thought.
I'm more of the type of person who prefers giving and getting closure than leaving on an uncertain note. In fact, since I've avoided the synopsis for the final issue like my life depended on it, I was beginning to think that somehow Penguin, Harley and Ivy were ALL going to carry out their threats. I must admit, the "I'll get you" line sounded a bit corny to me, especially when repeated, but now that I know why you wrote them in, I appreciate them more. There's no denying that "I'm ending the Harley and Ivy partnership forever!" has a dramatic ring to it.
As for my idea of the wedding, you're right about the confines that go along with only having 17 pages, but I'll fight you on the "manipulation" angle

Harley's smart enough to know that Joker wouldn't ever really marry her (seeing as how she hated it when he was being genuinely affectionate towards her in issue #3), and would have guessed from the start that he was only going to marry her for her money (after intentionally informing him of her amassed wealth via the letters strewn around her cell). Her double-cross would then have been spending all her cash on the elaborate wedding, only to inform him that there's nothing left once they tied the knot. Chances are though, he would have figured out her scheme before she managed to get down the isle in her custom-made dress...diamond-encrusted, of course.
I'm curious Ty - where were you ultimately hoping to end with these characters, if the series wasn't coming to an end? I know Dan mentionned plans for a Red Hood/Joker showdown, and you hoped to wink at
Return of the Joker's continuity by having Tim survive an encounter at Arkham, but what about Catwoman, Riddler and Penguin? Has your intention always been to leave them in a position where they would continue on as they always have? Or do you secretly wish Harley and her puddin' could have settled down? Who would you have killed off, if anyone? What other significant twists would you have thrown in down the line? I can imagine plenty of scenarios in my head, but I'm much more curious to know what the 'end of the line' looked like to you if this series had lived on indefinately. What if
Batman Adventures outlived
JLU as the last surviving part of the DCAU? Would you have integrated whatever conclusions Timm and his group had in store for the characters into your title, or followed in their footsteps and avoided being "tied to their continuity". Did you even plan to stay with BA until the bitter end, if you could?
I ask a lot of questions.
