There are systems of lighting trusses that can be raised and lowered as you describe but I have not seen it in a track system. That does not mean it doesn't exist, though. There are numerous lighting consultants that could specify such a system for a new or renovating building, but adding it without major demolition work is likely to be very difficult.

I wonder if anyone has heard of, seen, knows of a multi-functional gallery space with a 16 or 20 foot high ceiling with a drop ceiling with built-in track lighting that can be lowered (pulley and/or motor?) to 12 feet for a more intimate space for installations? Assuming the "real" ceiling beams can support the weight, the supporting cable, pulley and/or motor system, track lighting, and electrical wiring should be possible to install. Of course, this may not be economically feasible or may be crazy to try to pull off . . .
