Select Fire R/T?

After reading a few pages of Brihard's thread on (what is known as) the blender mod, and how apparently someone got it to work, I came up with an idea:

Call me crazy, but I'm thinking about trying to take the R/T on my gun, and make it select fire. Someone in the aforementioned thread made a remark about putting a flow control valve on the R/T to make it select fire, instead of Brihard's idea of turning the blender mod into select fire, where you can change it from full auto to semi.

I'm going to take this idea and try to run with it: perhaps I can put a QEV where the flow control is on the Response trigger, and control the flow to the R/T from there. The problem with this idea is this: I'm not a guru on QEV's at all, and if anyone knows exactly how they work could help me out, or give me their ideas, i'd be greatly appreciative.
Is there any way I can limit the QEV to partially vent at a predetermined pressure, or is the QEV simply an on/off type of valve? (I'm asking if the QEV works similar to a wastegate on a turbocharger setup: it's set to vent at a predetermined boost level, but when it vents, it only releases the excess boost. so once you surpass the max boost, it vents off excess, but doesn't completely vent off all presssure.) So, back to paintball: if I want to fire at, for example, 8-10 bps, the QEV will vent a decent amount of air, but still hold enough pressure to activate the R/T at 10 bps. If I want to increase it to 15-16 bps, the QEV will still vent some air, but not nearly as much as it would if you were shooting at 10 bps. And if i just want to run Semi-Auto, i can turn the QEV all the way down, and it'll vent any gas that would normally activate the R/T.

give me your feedback. perhaps this is a really dumb idea, but i think it might work.

theres a easier way to do it then that alls you do is tune the r/t to say full auto and the make a mark on the gun then tune it so you only get a 3 round burst then put another mark on the gun so on and so forth. then alls you have to do is carry around the screwdriver or get like a toy mp5 and take the select fire switch off and mount it to the flow restrictor.
