Milling an aluminum Classic Valve?

[OPBN]

I'm not looking for a lower cost alternative and an X valve will not work as it has too many holes that would have to be plugged. I simply want the reg off of the back of the marker. I can accomplish this, and have by simply taking the reg off of a Classic valve and capping it, but I would rather have something that I can have anodized.

It should be easier/cheaper to use the original powertube. You can't see that portion anyways. Didn't know if you were planning on doing this already.

I thought I had mentioned it, but the ONLY thing I am asking to try and get milled is the "valve" section of the valve. No regulator, no powertube, no internals. Essentially a housing with an input threaded hole, a hole for the on/off and a thumbscrew hole.
