Well, you know people are going to say:
"why the heck did you do that?"
"why didn't you just buy a cocker?"
Unfortunetly, they don't get it.....
One idea that might be neat is to build a sleeper-blade, and hide the pneumatics.
For example, hiding the ram in the pump, and hiding the reg and 3way in the grip. Then, maybe using a 4oz instead of a 12oz.
So, it looks basically like a stock Blade..... (That would really surprise a few people!).
Though... it would probobly be easier just to gut the Blade, and stuck a mag inside of it, but where is the fun in that????
