There must be enough length to accommodate the tang screw and perhaps a filed finial behind that. And the tang screw must pass through the tang and the stock at 90 degrees to the tangent of the tang/wrist and intersect the front end of the trigger plate. These things shall be verified in your blueprint-drawing in your planning stages. Having more steel behind the tang screw and finial, is not useful or desirable....in a Lancaster rifle.
