I did a thread about a Marvel / Star Wars crossover. What about the other side of the coin, and lets take advantage of the fact that James Kirk and Steve Trevor were played by the same actor, and lets establish in story that the two characters actually look alike. Wouldn't that be interesting? Wonder Woman is going to think Steve Trevor came back to her a third time, and you know Captain Kirk, he will just roll with it, and you might get a jealous Bruce Wayne.
We'll need some bad guys of course to drive this plot, any suggestions for the Justice League and the crew of the Enterprise working together to fight a common foe?
I think DCEU Earth don't have a lot of starships, could the Kryptonian ship fit within the Enterprise hangar bay? What do you think?
