I read it over, because I love Marvel, but all the stuff you mentioned took the game too far away from Sim for me to enjoy it. Even though I'm ok with genre emulation in supers games, MHR took those narrativist mechanics too far for my comfort.
Problem: Superhero universes do not generally operate under consistent physical principles to simulate. Comics, as a form of modern mythology, operate as they do because certain narrative conceits are applied - simulating such a universe would generally call for including mechanics related to those narrative conceits.
