I doubt it will happen but I love the idea of the Justice League accidentally crossing over into the Seven's World and I love the idea of them meeting Homelander and the others and slowly realizing that Homelander is crazy and homicidal. I also would love to see Superman fight Homelander it'd be beyond epic. I think a crossover like that would make for a long and interesting story arc and I can definately see Bruce working with Butcher to a point.
