Serious question, although I probably will never face such a predicament: Would running a standard 10 x 1 (25.4 tpi) 60° die just over the damaged outer threads help, or would it make matters worse and cause mobs of angry C&Vers appear with torches and pitchforks?

This isn't idle speculation; I've done it multiple times, and Saint Sheldon himself has approved this.
In my conversations with John Allen, I seem to recall he experimented with zero axle showing past the lock nut, and with a firmly-applied QR no issues or movement at all.
