Adding t5s to radion xr15s?

[g8rorchid]

I recently bought 2 Radion XR15s for my 90g reef. I have been playing with the templates quite a bit and I'm just not 100% happy. I think I need to add 1 or 2 T5s. I have the XR15s on the RMS arms - is there a way to add T5s to this setup? I don't have a canopy and can't hang anything from the ceiling and would prefer not to make holes in the wall. I would also hate to not use the RMS arms as then that was throwing away money. Is there a way to do this? Or is my only option to get a simple 2 bulb fixture and just lay it across the tank?

I only have basic tools (I'm a single gal) and I'm not handy, lol. I have seen folks gutting fixtures or building hoods, but I sadly feel that those kinds of projects are past my ability level.

Any help would be greatly appreciated! Thanks!
