I think the Osiris did work in the way you mention. I believe the pnuematic hammer was a single acting cyl and was spring returned?
I cannot answer if that will work specifically. I am considering doing similar but the goal is one lpr with all operations at the same lpr pressure.

By supplying an LPR with a short blast of measured pressure, the measured 'blast' from a 3 way, the only question will be if 'recharge' time and the volume reaching the target actuator will be sufficent for operation. I beleive the Palmer microrock, with a smaller internal measure, will be able to achieve that, but I know of no prototypes to go on anyone's experience, or if the osiris worked this way.
Normally the lpr is a constantly charged state and the available pressure is switched after the fact, which I would think is a more consistantly reliable method, hence the consideration of multi-way valves.
The osiris specs are listed as a '3way' though, which would indicate the secondary pressure regular just might recieve one of these channels.

I think that regulating the air for the return will work however you are going to have to wait longer inbetween shots so the reg can 1. pressure up, 2. actuate ram, 3. dump pressure when the trigger is pulled next time.
You are going to have alot of waisted air in filling the reg, pressure line, and ram for every shot.
Id reccomend using the PGI kit or better yet just get a proven and reliable front block kit. PPS, ANS, KAPP, and ST all made great front end kits.
If chopping really is a major concern then perhaps you should tune the gun up and spend a tank or two just firing in fast and slow speeds, Make sure to listen to the gun and feel your fingers on the trigger as you do this. In the end a finely tuned gun will beat a novelty gun. Including reliability, parts availability, and servicing.
However if you want to improvise your own pneu switch id like to see what you end up with.

the osiris is a pre-mq valve mq gun.
it works like a close bolt timmy. the ram on the front controls the bolt, and there is another ram in the bottom cyclender like a timmy to drive the hammer.
there are 2 lprs because then the ram can cycle with a tiny tiny amound of pressure and never chop, and the popit ram can cycle with the force it needs to open the popit valve.
wow, seriously? leave me the **** alone.

Actually, fitting a hammer to the ram is easy, making it fit is hard.
I'd love to get an Osiris to finish my PGI collection but I wouldn't pay much just so see how they did it. I'd still arther have a finicky MQ.
