Not to be a killjoy here, but unless I'm missing something, this doesn't sound too horribly complicated. I'm guessing that the electrical solenoid in the cocker version of the Q valve is positioned where the hammer would be. The pulse pushes back against the valve stem, which is sealed via the air pressure on the cupseal. To prevent too much battery drain, a spring could be used to naturally push against the pressure of the charged air chamber. This jives with all the tech specs I've seen.
With a mag, you'd be using the same "large solenoid valve" idea to dump into the dump chamber, with no sear, so that the act of dumping actuates the valve and pushes the ball. This also seems to jive with what I've seen (no sear assembly).
Of course, the freestyle from ICD is pretty similar to a mag...A similar style retrofit is probably possible.
