Taking it a couple of steps further, a solenoid valvetrain would make cylinder deactivation a simple affair. Over on a couple of mopar/hemi forums the general concensus is the the hemi would cruise just fine on 2 cylinders, the penalty being engine vibration. The engine could also switch between otto cycle and atkinson cycle depending on demand.
