I have a pantograph machine(duplicator)and most set ups require at least gluing some pieces of wood to the existing stock temporarily. A careful craftsman can remove the blocks after the duplicating process and not leave a trace. While I do not like running nice stocks through my machine as patterns(accidents can and do happen)it can be done with lots of careful set up. As to correcting the cast, it can be done on the machine or through a bend. All stock bends have some risk associated with them as well but usually bending a Parker with a sound stock for cast is not an issue. Hope that helps,
Steve
