David,
I had my CZ Bobwhite bent. It is my field gun I use that I don't care if it gets scratched up unlike my sterlingworth or Remington side by sides. I had a 1/4 of cast off, and the pitch changed.
As for camber, I saw one in the above post showing the various jigs where they were twisting the stock to take the camber out of a stock.
I see no reason it could not be done. My dad and I sometimes bend wood in several directions when building horse drawn buggies. The amount of twist would be pretty minimal I would think.
