Don't torture yourself.
Honestly, I'd rescue the medallion and turn it into a throw or lap quilt or similar. It is absolutely stunning.
As for the butterfly parts, can you cut 'blocks' of a decent size with the finished/attached ones as a centre? They don't necessarily need to be the same size block. I'm thinking cut it into useable blocks then see if you can pass these on to a local guild or Linus Project group. If there are any un-appliqued ones they could go along too.
