Wonder Woman and Batwoman team up?  Yes, please.  Simple concepts work for me...Such as fish out of water story with Wonder Woman having to spend extended time in Gotham with Batwoman serving as her liaison.  Another option is  Katherine somehow finding herself in Themyscira.  I can see Katherine having quite the adventure amidst Amazons. Another option is the classic team up with them against a villain or an assortment of villains.    There is, of course, the scenario where they pitted against each other somehow in iconic battle that serves to be a misunderstanding that results in friendship, or possibly more.  These can all be generic or complex, we can play with them and work out deeper stories I'm sure.
