I think a good T5 setup could sustain whatever you like, but with proper placement......T5's have been proven and used on SPS dominated tanks, so yes they are capable....As far as MH not a bad choice, but that's dependent on your canopy setup/design, but definitely wouldn't purchase a MH/PC combination.....PC bulbs are horrible.....
As far as LEDs another super choice.....You don't have the heat issue that could be associated with MH's or the costly bulb changes, but as far as longevity and electrical payback that is questionable......
