I have a 125 gallon with three Radions G2 pros(the middle one has been upgraded to G3 pro) mounting on the RMS rail. I checked on the Ecotech forum and it seems the upgrade kits to do the other two lights are no longer an option 
One thing I've been considering to get better coverage(eliminate shadowing etc..) is to mount a light bar of some sort to the front of the tank side spanning the full length of the tank and angled back toward the rockwork. I have to figure out how to make a bracket to extend off of the RMS or off the xr30 themselves. My question is what would be the best spectrum to supplement the G2's with. I'm currently running them with the coral lab profile with a peak of 50%(thinking of dropping it down to 40%) SPS AB.
Currently looking at Reefbreeders, SB Reef, GHL, Orphek, Reef brite, and Vitamini as possibles. I supsect the Vitamini might not be powerful enough to have a meaningful effect though.
