While I agree this crossover should be on earth 38, how would it play out? Arrow + Flash randomly decides to visit Supergirl then they're called out to help in another city? Then they call out their other team members too?

My reasons for wanting it on earth 38 are not the same as your but for character reasons. I do want Supergirl characters to have more impact in the crossover rather than just Supergirl/Alex.

On a separate note, Supergirl needs to crossover to Arrow to take out Ricardo Diaz - should of done this in season 6.
