I, too, want the crossover to happen on Supergirl's earth. That way everyone can meet all the different aliens - Diggle can have the most amusing reactions. Cat Grant should have a role in the crossover. She'll have a field day with all the superheroes. I also really want Felicity and Cisco to meet Winn/Querl Dox.
