Bent a/c compressor pulley

[Nayr747]

Part of the outer lip of my A/C compressor pulley is bent in for some reason and causing noise/damage to the belt, so I'm wondering if I can just replace the pulley with one from a used compressor without taking the compressor off the engine, dropping the engine, having to refill the a/c, re-oil the compressor, or replace the compressor bearing. It seems like there might be just enough room between the pulley and frame to remove the bolt, but I'm not sure.
