The device I'm thinking is a small electronic solenoid to strike the lever at TDC of the compression stroke using a pickup off the flywheel (that will strike every stroke). Running off the cam would be better as you would get an exact hit per 2nd revolution, but is harder to setup.
Holding the lever down simply won't work you need to use the compression to stop the engine before the compressed air pushes the piston down.
Sensing the pulse of the injector I'm thinking about, but remember when throttle is closed no fuel should be getting delivered meaning no pulse - but does that mean no pulse at all? Using a delayed circuit should get you on top dead center!
The other device is a simple butterfly valve in the exhaust, but wouldn't the clatter of a compression release brake sound better = cowboy stopping style.
Its and idea that I'm now going to work on. I'm also hopefully erecting a work-shed/garage, so lathe and mill will follow allowing me to work on compact blowers for engines "HOPEFULLY".
Just remember "Problem / Solution"

Please give me feedback as it is very welcomed. It gets very quiet here on prison island = Australia
