Sure, but that seems to be one way of getting at what's going on in Squirrel Girl if you want to run a version of that in MHRP.The idea of having Doctor Doom be a minor character... it boggles the mind.
I'm not advocating for that (in general) and am not advocating for a Squirrel Girl game (in particular). But I think it is one of the devices that MHRP has available that helps answer the question that was asked.
Somewhat similarlly, if I was running a game with The Punisher, Cloak and Dagger I think it would be reasonable to apply/interpret Vehicle, Science and Tech skill in a more constrained way than if it was Iron Man, The Fantastic Four and Spidey.
I see this as part of what makes MHRP a better fit for supers (and frankly a lot of other non-gritty genre stuff) than GURPS.
