I'm imagining that Batman would have some sort of (highly conductive)superglue/titanium foam shot from a nozzle on a aerosol can to keep thor from his hammer fro 60 seconds. Now it might be possible that Thor could rip the foam off his hammer in under the minute time limit, but it's more than possible that he'd rip most of the flesh off his bones trying to extract these balooney titanium mittens from his hands, which would mean there is no no medium to keep his bones from falling off.
The obvious revision on Thor's part is the transformation to Don Blake doesn't side step this trick is: Can he pick up the hammer with his toes?
