I've used my laser cutter to cut a mask for acid etching when the laser itself couldn't etch the material needed.

How thick is the rubber you use for sandblasting? Could it be laser cut to reduce the pain of making the mask? It sounds like you've exhausted all workable options but my curiosity is piqued.
