I'd still fix the tin and make her whole again
I didn't even look back at the pics before this post, nor am I a body man....well, I am, but a different kinda body.....
Anyhow, while the 80 shell (save the windshield cross bar) is tough enough to survive in a violent roll or flop, with redundancy inherent the namesake, it's possible that a PS D pillar crunch could impact the DS roof at the A, B, or C.
Bet a close inspection of the door reveal at hatch and/or DS rear would show movement.
If we're taking about sectioning out the exterior sheet metal, scabbing a patch on, bondo and rattle can, so be it, BUT, my opinion is this type of damage may impact its ability to protect in a more serious roll, in the future.
Once they've flopped, time to bob it, chop it, and cage it......or move on to another that's not been compromised.
