Yes, probably a good idea.  Even cars are moving to higher voltages.  If you design the end items for the buss correctly, you could use anything in the range - Call it 13.8-48 volts (keep it below the 50 volt 'high voltage' limit).  

Again, I think the control signal could be Zigbee (which should work in high RF environments, is a fairly well known standard) and with, say the option of a Dallas/Maxim 1-wire type buss.

BTW folks, in case you don't follow it, Zigbee is probably what your local 'smart' power meter (and water meter etc) is using/going to use.  Ultra low power demand to the radio, good signals, and they can setup as a mesh network
