Maybe you could make an overlay of just the bad section until a better playfield can be found. I think mr pinbologist has used this method in one of his restores have a search through them.
If his threads can't give you any ideas no one can. Good luck hope you can sort something out
An overlay for the badly worn section is one option, though a scan or a good picture of a good PF would be needed to create one from. I tend to only repair a PF this way now as a last resort. I used this method on my Stern Lectronamo restore.
