You shoud be able to get away with it. If you plan to do it later on, just run conduit to the center of the location you plan to do it at. You can have the light unit at an equipment closet and then feed the fiber thru the conduit. My star panel was more of an after thought because I thougt it wasn't going to be an affordable option but when I found a kit at Starceiling-designer.com I was able to rework my ceiling to make it happen.
My ceiling was 7'6" before adding strapping and sheetrock. It is mostly centered over the front row but you get a nice view of the star panel for the rear row as well, like looking out a skylight.
My light units are the RGB models which are able to produce multiple colors.
