YES for the showdown.
You should write a POV of either Maria Hill or Clint Barton's thoughts about the war and its consequences on the rest of the world
Might be interesting if you make an evil jinwoo. Maybe his mother died in an overflow and he didn't make it in time to save his sister at school so he went crazy. Also Hela having a summon that can summon his own army might be cool. So yes.
