Thor has absorbed omnidirectional blasts before. He's also absorbed a blast that hit him directly, not the hammer, but was holding the hammer and using it to channel the energy through him into it. He really is the deus ex of absorption feats, though that second one is ignored by most writers.

Wasn't Thor's absorbing limit reached when he aborbed Glory's blast? He reverted back to his mortal form after doing that feat.
I'm pretty sure that was everything combined, not just the absorption feat. Besides, that was pretty much an abstract he was facing, it's a bit hard to quantify the feat and is quite possibly better than anything in the OP's list.
