I made it by 3 body shops today.
#1 said they could make an appt for me for wed morning.
#2 went and got his lead tech/manager. He explained that he wouldn't repair it unless they also changed the roof. He suggested that one might think you could press it into place, but he questions the structural integrity of that. He would get me the relevant quote tomorrow morning.
#3 said it didn't seem like something he could do, but "let's take a look at it". He said the proper way to do it would require a roof replacement, but that would be about $3k-$4k or more, and his shop isn't set up to handle that. "For my money", he said he'd press it into place, bringing us back to the suggestion of silversasquatch. He mentioned that the adhesive used between the support and roof is "foam adhesive", which he expects that I could pick up at an auto parts store.
So I think I'll try to clean the residual adhesive off, maybe use an angle grinder with wire wheel, then press it, heat it, cool, relax it, press it, heat it, cool, relax a tiny bit, apply adhesive, press again, and leave it pressed for a (few) hour(s).
Then repeat with the other ones. I have 2 bottle jacks, so maybe I can find another piece of pipe to get another one going.
Side note, I took this waiting period as an opportunity to apply sound damping material and replace the interior lights with LEDs. Here's a pic, because everyone loves pics.
