...Just have to put the internal valve again to go back...
This was just a
blue-sky idea I was dreaming when I was converting the EDO-04 (SCR) to XCR (mCCR) a few years back...
I wanted to be able to switch between the SCR and CCR modes easily and almost instantaneously at will. And as you said, the only thing needed to be changed was the mushroom valve for the small bellows. And I started dreaming about a mechanical lever like the red-filter inside video housing that could slide the mushroom into and out of position...
You all could start laughing now...
