Anyone ever used a larger diameter pump tube on their 1377?

[cpu77]

I am sure it been done but wondered if anyone had used a larger diameter pump tube/valve/piston on their 1377?

I was thinking a modified 2260 tube (Same Length as stock 13XX)? 

What could you use from the 2200 series?   Hammer? I would need a custom Valve and Piston.  Anything else?
