Have you considered that room tuning panels, which are efficacious, can be made more artful? You can get them custom made with prints of your choice on the fabric, and can even frame them to appear like artwork. If you had not hear of it, I suggest you check it out. I believe there was a company I saw several years ago that would let you put your image on the fabric. I am guessing that with today's tech it wouldn't be that hard to get a printer that does fabric to put whatever image you wanted on it.
If you are handy this would not be a difficult task, and could be an agreeable compromise solution if the roadblock is aesthetics. :)
