NICE WORK HEINOUS!!! She's a peach as she is, the micromag body blows away the sydarm body as a base!
If I may suggest though....
You know me!
Within the limits of the build i'd mount your ASA on a $10 45 degree rail adapter:
First using a rail extender like this to extend the rail far enough toward the back end of the valve for the changer to clear:
This would angle the changer downwards at the back, fighting liquid. That would help a bunch, IMO.
Outside the limits of the build, the 45 rail adapter plus a palmer regulated changer set to give 850 psi would make this a truly fine pistol capable of keeping up with any shooter!
It's a winner of a job, all contests aside!
