I wouldn't have one operate the way an MQ does, but doing something similar is relatively trivial. It's how I did my mechanical Aedes, essentially make the lower tube the same as my closed bolt ions but with a valve body instead of a powertube. Can be done with or without isolating the dump chamber as long as it is dwell controlled with either a solenoid as a pilot or a pulse valve.
