When is a caliper no longer rebuildable?

I'm considering rebuilding oem rear calipers which (should) have 100k on them.

However, there is a measurable amount of rust, and after removing it (sand blasting) I'm not sure if the dimensions will change enough to effect the pad "glide slots" (or whatever they're called) and pad spring tension. That is, will it be possible for the pads to have too much play from the widening of the glide slots and the spring lip (I suppose the spring could be bent to compensate)?

Thanks.

I don't want to attempt to restore them until I determine if there is going to be any issues with all the lost surface area (like with pad glides or spring clip being too loose). Rebuild kits are almost free compared to the cost of replacements, so am seriously considering. I've used a sand blaster before, it's just care must be taken to not get sand where it shouldn't be, like in the piston ports.
