I am sorry I can't resist. Yeah that would work since there is a neutral at the load good thinking. Also for that tiny drain current required to listen to the line (x10 bus) you could stick a tiny inline milliampere fuse to the copper ground wire. That neutral doesn't carry any load current so the fuse is there just in case of a catastrophic failure of some sort. You always want a functional ground, not one that is inadvertently returning load current to the breaker box. Totally illegal btw.
