Yeah, that's exactly what I was thinking. I found some panel mounted push button 4 ways (well, MSC calls them exhausting 3 ways...

That would work. I even have a brass 'cocker ram and an mysterious adjustable LPR....Now it's just getting up the courage to drill holes in the non cart valve body...

Perhaps I'll switch bodies. I have a cart valved body around here that I've been meaning to tinker with....Maybe making a new valve cart nose is in order....(I've also been toying with the idea of a completely reversible semi conversion. I have a couple of those "dummy 12g w/ a forward stem and it's own co2 nut", and then I found some brass "stree tees that I thought might work out well....We'll have to see...)
Catchya on the Flip Side.....
