it would be nice if it were a bolt on, needs a good position sensor though, and its own brainbox, but is doable IMHO.

I would like a system where the valves stayed closed when the power is off though, so the piston doesn't bend them accidentaly when the power/brain is off. but computer control of each valve would open up some huge efficiency potential (and ugh, yes, performance), would make a vtec look like a flathead.

but some old guy and his lawyers probably already thought of it and locked it away in a patent till their demands are met. A bit of reverse-ageism built into that system.
