As per title.
I think it would be neat and I am not sure it'd be controversial to let spells like GMW, Bless Weapon, Keen Edge, Dark Fire, Holy "Sword" to work on our gloves and maybe even the unarmed state if possible. It keeps certain concepts from really being meaningful or viable. If you wanted to be a Seeker cleric of Malar who hunts tooth and claw none of your magic benefits you. Or a Paladin of Ilmater who wants to smite with his fists can't use what is effectively "what is good about paladin", holy sword, on his hands.
Along with this Magic Fang spells could probably also interact with unarmed - but I also wish you could apply those to any "creature weapon" so your empathized helpers, companions, or shapeshifted friends can get buffs. But probably also unarmed strike.
I don't have numbers or mind for anything balance-wise but overall I am not sure if you could AB or enhance gloves it would destroy everything.
Also - let us put poison on gauntlets.
