CF and PC are the same, just different names. Remember, additional T5, VHO or PC isn't necessary.
I don't like canopies either. Two pendants (not spotlights), fired from the same ballast, may be an option other than a single long fixture. For example, the Ice Cap, Sunlight Supply or Hamilton pendants. No adding T5's with those, though.
The Aqua Media Oceanlight 8 inch 2 x 250 Watt MH + 2 x 54 Watt T5 (AQ1831) is almost your dream light... but has a magnetic ballast. And it's darn good looking.
Or the Current USA 48 inch Outer Orbit 2x150w 10K HQI-MH w/ 4x54W T5 HO & 18 Lunar Lights (CU01072)
If money were no object, I'd for for the Giesemann Infinit
