I think you might be onto something there in infinite Crisis didn't Superman and superboy prime think Nightwing was the only good one left in that DC earth?
I think Hulk was the first one to lift it i think, supes could, anyone good and honorable and wouldn't intentionally kill people, idk how mangog does because he's a bad guy

Captain Marvel and Wonderwoman may have the best chance to be deemed worthy because they are powered by the gods. Superman is my third choice for obvious reasons of worthiness.
The only people I'd say have a chance to lift it are Orion and Wonder Woman. Superman did for a bit in JLA/Avengers, but wasn't able to at the end. Since that was cannon in at least DC(and arguably Marvel), I don't think he would be able to again. WW and Orion seem to fit the description of 'worthy' by Marvel's Asgardian standerds, but I can't think of anyone else who does.
He doesn't have to be...he's above the hammer's enchantment. I'd say Galactus could pick it up as well.
