I can't imagine Matt Murdock lining up with the likes of Thor, Sam Wilson, Captain Marvel, Ant Man and The Hulk against a threat like Kang. It's hard to imagine him doing that. Plus, I am curious to see what his reaction to aliens and wizards would be. Same situation for the Netflix characters. What exactly would their reactions be to Thor, The Guardians, Dr. Strange and Wong if the Netflix heroes were all to show up all of a sudden? If I had to guess the reactions to aliens would be like the others the first time they met aliens "well, they're here" and move on. It would be like the first time Bucky saw Rocket in Avengers: Infinity War. They might have a different reaction to the sorcery of Strange and Wong.
