VGA cable length

Many if not most DLP projectors have a VGA connector that accommodates component signals. From what I gather, there must be a short pigtail that you use to connect to the three BNC terminated cables. I just bought a house that has a theater room where the projector was wired with a single composite cable (must have been one of the first projector systems) and I'm not sure how difficult it would be to run three component cables through the ceiling and wall. My question is, could I expect good results if I ran a VGA cable to connect to the projector? (The run would probably be about 10 to 12 feet.)
