Not practical.

The copper is bonded to the fibreglass/phenolic using a very strong adhesive and more often than not you will tear the copper before it comes away cleanly.

Even if you could get it off in one piece, the next issue is applying it and gluing it successfully onto the board.

cheers for the feed back. circuit trace repaired at the time of the post.
it is as you say unpractical but hay a cb user is happy with a super glued trace. and the cb is stable now, so what is practicality.

If the trace is big enough I suppose it would work. When I think of PCBs these days I think of very tiny narrow traces that don't stand up to any heat etc and are impossible to repair even with wire links.

Glad it worked for you.
