This is an economics and time issue. I'd follow the fitter's advise and not try to bend more than the wood wants to. I think you might find you can have a new stock made to your dimensions from a decent piece of wood (don't shoot for the moon on your first one out - use it to learn) for an economical price. The compeating plan will be to sell your gun and buy a different one. Compare expected extra cash outlays between the two plans. A piece of plainish wood of good quality is not expensive and basic duplication, with sufficient overage for experimentaion is not all that bad.
