In this question, Comments suggested that a creature with feat Improved Unarmed Strike that wanted magic weapon special abilities for his unarmed strike get a pair of masterwork gloves, have them given a magical enhancement bonus (presumably by the spell greater magic weapon which may be able to target the gloves as improvised weapons?), then get the now +1 gloves imbued with magic weapon special abilities.

Assuming that the creature makes its unarmed strikes exclusively with its fists (although any creature can make an unarmed strike with different body parts), will this process result in the magic weapon special abilities applying to the creature's unarmed strikes?

Likewise, can a similar process be used to make masterwork clothes with magic armor special abilities? (Although these obviously won't have any effect on the creature's unarmed strike.)
