Well, to me that is a super easy fix, ie, i work at a body shop with 4 frame machines, it would be really easy to fix, just pull it to within spec, hammer out the sheet metal perfect, sand off the broken paint, small amount of filler if necessary, but it is highly frowned upon on structural work, but since all that is cosmetic and not structural. It is like pulling paper with a good frame machine. Its gonna have to be pulled, no way around it. core support may be saved, but I'd hammer/dolley it back straight and then replace the panel between the core support and shock tower, just drilling out spot welds and if you have a spot welder,you can put it back in within about 30 min. but if you do plug welds it will take longer to do since each weld takes longer to do, and then you have to grind them flush.
But why am I saying this, you're not going to do any of it lol.
