I remember the teardown of the 1st Sony 70-200 2.8.
Possibly the worst report ever.
Not so much that it had obvious weaknesses, more that he hoped he'd never have to work on one.
(This finding was not typical of Sony lenses)

Unfortunately Roger Cicala stopped doing his incredible lens teardowns, where he would take apart a a lens and show in detail how well (or not) it was put together, which would predict how rentals of the lens would fare for the normal wear and bumps it would see being shipped out and used. He would often find some disturbing aspects to the construction that wouldn't bode well. I don't recall how the Sony models did on balance.
I think looking into this makes a lot more sense than encasing in acrylic.
Using the GM 24 less due to it's similar appearance makes no sense at all.
Maybe change to Nikon or Canon due to the lenses having a different look?
Sorry for your loss, but get over it! Or get into Holgas.

I'm thinking a fairly small bump is more an element misalignment as apposed to something that broke. Even non-working parts-only lenses have value on Ebay I like photography for relaxation, I wouldn't personally find it relaxing to open up a lens and look around, but I could see how some might. I guess to a repair shop a more obviously damaged lens might be easier to repair.
Looking at the teardown of a 135GM, I found it interesting that even though the problem was identified as an element that popped out of alignment, it was not easily fixable. The teardown also gave me some insight into the construction and complexity. I used to enjoy taking things apart to see how they work, still do to some extent. If I thought I had a decent chance of a simple fix that might be an option. Looking at repair, I'm guessing labor + parts would be in the same range as a used copy.
I'm guessing sale on Ebay with disclosure is probably The best option. When you get to landscape apertures it is still very sharp. Looks like today will be fairly clear out, good day for further testing vs zooms that cover 35mm to see how this lens now ranks.
