This is probably not a good idea, I can see several things that can go wrong.
You start the process, but how can you tell how far to go to remove? You could end up with a toothpick-like stick by the time it's all out. And let's say you start to remove material, and it's deeper or more color ranges than you though. You would want to stop before the stick is a 10oz one, but you end up with worse color than you started, than the thing is ruined.
As someone else said to another person here that wanted to change their stick by removing decals from the finish, sell the stick, get one you want.
