electric valvetrain?

Looking at a set of pintle style 2005 5.9 RAM diesel injectors.

Im thinking these are heavy duty pintle servos that open a high pressure fuel rail port to each direct fed cylinder. What is the chance these will morf into direct no spring intake/exhaust valve actuators for an infinitely variable lift and duration valvetrain? Maybe start on a small low mass valve, low RPM OHC lawn mower engine run by a seperated Megasquirt running the duty cycle of the valve 'injectors'? Maybe use turbo or exhaust back pressure to assist as a pneumatic assist for the valves..so the pintle controls the pneumatic pressure to the low mass valve "lifters"? Maybe lower mass slide valves? Just spitballin' here......

When I worked at the local Chevy dealer back in the late 80s, A couple of us went to the GM training center in Atlanta. They had an small block engine set up on a run stand. It had solenoids on the valves instead of springs. It was totally electronically controlled. Camshaftless. Just had a TBI unit on it. Had some kinda crank trigger ignition and a plug in the distributor hole. They could fire it off and and enter different inputs into the controller and make it sound stock one minute and hot a hard lick another. It was pretty cool......but I haven't seen anything like it in the market yet.
