Your right you do need to be worthy to pick up the hammer and Captain America and Beta Ray Bill have done it in the past. So Superman could but when they had him beating Thor that was just too much to take, although the other marvel superheros did jump him and beat him up to make up for it.

I think Storm beat Wonderwoman which I would doubt, Wolverine beat a DC guy, did Batman draw with Captain America? Namor lost to Aqua man which again is highly dubious.
