Right now I have the 250 watt hps 1 foot above the plants, seems to cover the area well, the 150 hps is the same height but near original tops of the plants, as I have a bunch of seedlings, clones under it untill I switch to 12/12.

SmokerE. A cool tube would be the bomb. but I'm happy with my room temp it's been averaging 74-76. Today a new xbox 360 has priority lol.

The plants wouldn't absorb the light from the bottom side of the leaves, but the principle would be the same as the current light setup, wouldn't it? You're still not illuminating the other half of the plant (call it side #2 if you had split it down the center while growing normally, straight up) except for what reflects off the floor, though that is probably negligible. It seems that floor lighting would be less practical for the heat/space issues. You have a lot more room up top in the room that at the floor, and you may even get lucky and have the branches currently facing down start to grow towards the top light. Not many people seem to keen on LED's on this forum (i know, they're impractical and not efficient blah, blah, blah) but it seems that for "floor" lighting, if you could find either a cheap array or build one yourself, this would alleviate any concerns that would come from placing a HPS lamp there. Really cool idea! Will follow your progress...
good luck
