Looking for a way to alter the size category of gear in game.

[Zomburs]

Is there a spell or a way that would shrink a large weapon to a medium weapon, or the opposite. Playing a small class size character the majority of the gear you come across is going to be the wrong size for you. It would seem weird that no spell caster or w/e has come across a way to change the size category of items in Golarion.

There's always shrink item, which would be perfectly reasonable to allow the caster to choose how much the item gets shrunk. But also, have you read this? Generally speaking, size and equipment isn't an issue as far as loot is concerned.
