If you base the JL movie off the Thanagarian invasion, you will have to introduce Hawkgirl, John Stewart, Wally West, Wonder Woman, and the Martian Manhunter. You will also have to create a Stewart/Shayera romance.

In comparison, Avengers only needed to introduce Hawkeye. Everyone else already had their own movies.

It will never work.
