Mr Miagi
Veins are flowing with SW, now going back to FW!
Personally I don't see the issue. Its just an upgrade of lighting. Its not going to affect any corals, you wont need to photo-acclimate fish, so I cant see any dramas. Of course you need to get the initial steps you've already planned out complete, but your on your way, you know what needs to be done, and there is no reason NOT to buy a lighting fixture, especially if its not going to interfere with adding LR or sand.
IMO on the actual lighting unit, it seems good. T5's are better than T8's. More tubes means more light and more customization if you want to change the color, ie. K (kelvin) rating, and it has a fan for cooling, which is even better!
