Can I HANG my QUAD 57's?

Is this sacrilege? I have a pair of QUAD 57's. Which I love. But the way my place is set up it would be REALLY nice if I could hang the Quads from the ceiling instead of having them on the floor. They could hang quite low....it's just that there are other things that I would like to have on the floor space below where I would hang the speakers. (like a sub or potential pair of subs, but that's the subject of my next thread) My work room is quite large (27 x 24, but the listening area is concentrated in primarily one corner, and the quads would be about 15 feet away (from my ears to the middle of the speaker at hanging height) I would estimate the DOWN angle at about 17-20 degrees.

Is this a ridiculous idea or feasible? What will it do to the sound. Intuitively it seems possible....especially with electrostats vs. boxes, but......I just don;t know. It will be QUITE an effort to get them up there safely...so I want to find out if others have already gone this route.

The system....(work in progress...but I am pretty happy all around...)
