I read a book a long time ago about the hulk based in the facts in the comics, and if I'm remembering correctly, he has always had a limit, and I think it was like 20 tons or something of force, he was definitely listed as weaker and lighter than abomination. I don't like DC, (except batman) but superman would definitely win here. Take out him and Iron man and you would definitely have a much more even fight. Now, if you want to keep Superman in and make it pretty even, take out CA, and add in Gilgamesh or Quasar.
Gilgamesh is immortal and stronger than the hulk, and Quasar is basically halfway between superman and green lantern
