Back in 90 I was installing Star Fire ignitions on Ajax Industral engines. It was two magnets spaced at different time and the first magnet was to charge the coil and the second magmet fired the plug . All this off the flywheel. I've wondered if this could be possible with todays advanced eletronics on a smaller scale. Oh mind you they had different pickups for each magnet. Great system no moving parts.
Careful Fooped - your "experience" is showing now (is that a nice way to say "age"?). I have some Starfire / Ajax experience also (especially on the 2803 series - so what does that tell you about the pot calling the kettle black

) - never thought about that ignition concept for our purposes before but it could fairly easily be done I am sure.
