Sounds like a good idea, you will get more swept volume but with their design of having a hard piston head it there will be no shock absorption when smashing against the end of the chamber. Most new airguns have a polyurethane piston head for impact resistance and resilience. I would make a completely new design piston head from polyurethane rod.
