I don't think you can. If you have another CD on hand then it should still work with your old CD key, I don't see any reason why you'd want to change the number.

I assume there may be a way to do it but I don't think anybody would take time to figure it out. The game is quite old and you can find a brand new CD for $5~10. If you're worried about losing settings/replays, just back them up somewhere or you can choose not to delete custome files while uninstalling the game.
