Well... MAYBE if you made a larger powertube with larger ports AND a new custom cupseal to match it PLUS enlarge the hammer AND respring the whole thing... then MAYBE it'll work. But I predict that that it is a lot of wasted time and money for what is really little gain. Phantom internals are already made out of hardened stainless steel. A full-time custom airsmith I'm friends with won't tool a Phantom hammer or bolt because the steel is so hard it destroys most tools. : I know not many people make after market parts for a phantom since they are so good stock, but would there be a way to get a stronger power tube that lets more air through? : : With some tricky springing and a tightbore barrel I've heard of them going down to 650psi, but the powertube design is just too restrictive to pressure flow to go much beyond that. Opening up the air passages any more than they are will weaken the powertube and it will crack under use. I saw the effect of a powertube cracking while pumping... poor guy got a cheekful of liquid CO2 !
