As a Potter afficionado, it would be difficult to say on which characters would end up where because of works beyond the books and movies adding a bit more complexity.
As stated, Hermione was in Gryffindor despite her smarts, mainly because of the Hat giving her the choice between the two. The same thing happened to McGonagall when she first entered the school. We also see in the actual books at two clearly jackass Gryffindors that definitely go against what the house stands for.
A Marvel character can embody so many things that it'd be difficult to determine where they might end up. Who's to say that Spider-Man could end up in Gryffindor because of his bravery or responsibility to do the right thing? Or could he end up in Ravenclaw because of his smarts? Spider-Man can be loyal too, so does that mean he's a Hufflepuff? Or what about when his darker tendencies and ambition get the better of him? Is he Slytherin?
My Pottermore account ended up with Ravenclaw, which, after reading about what that house espouses beyond wit and intelligence, I certainly value and agree with.
