Sure, its possible, in the same way that its possible to get a Honda Civic to run the quarter mile in 11 seconds. All it takes is money.
I'd call up The Firing Line in Oklahoma. They have custom end-mills there that they use to mill through those hard milled recievers (they rockwell in the 40s, those receivers will laugh at a cobalt drill bit), and they can probably whip up anything you want. A fresh credit card will help alot.
