An inverted ascender w/ some weight clipped on it will automatically keep rope from going back through the pulley. I would be surprised if you could get a gri-gri to auto-feed with the rope running in a straight configuration (instead of the U shape that is usually required for smooth, rapid feeding w/o squeezing the cam).
Also, with all of the slamming around that can happen on wall anchors, I'd hate to have my pig be held in place by something that releases with a push of the lever, even under load. Camming pulleys generally don't release until you take the load off of them.
For really little loads, hand-over-hand through a biner w/ a butt-belay for rests works OK.
Otherwise, it's probably worth your while to have a pulley/ascender system or camming pulley.
(edit) The teeth of the pulley that you use to hold your supplies should expose you to much less risk than the teeth of the ascenders that you use to belay yourself up the rope...which is to say very little. You're (hopefully) always backed up to the lead line when hauling!
