It should be possible to control the lights via ERC, though it's probably a lot of work. What you could do is use a minimal figure (e.g. a figure made from a p4 square). Parent the lights to that figure and resave to a figures pallet. Set up master channels in the BODY for each light parameter you want to control (e.g. red, green, blue, intensity, etc). Then slave each channel in each individual light to the corresponding master channels in the BODY.
