Anyone convert Webley nemesis into pcp?

The crosman 2240 is similar designed. It had a tube where you place the co2 and screw cap in to pierce the co2. Folks were able to convert it to pcp with the hipac. I'm sure someone with the right tool could make a same design for the nemesis. Co2 is fine but i dont want to keep purchasing co2 when I have a compressor with infinity air supply. Also co2 gets weaken in the cold. And max psi output is 800 psi where as pcp would be 2000-3000 psi.
 
did you miss the part that Webley valve sits in a plastic housing, where as the Crosman 2240 has a steel tube that the valve mounts in and the open boss valve can then be sealed with O-rings and pined by screws from the outside of that steel tube

why would anyone waste there time doing what you what, by remaking a 100 buck gun

and even when someone converts a 2240 to air you don't charge them up to 2000 to 3000 pounds, 1500 would be tops
