Does anyone have any figures on what sort of load the 2 dead cylinders are? The reason I ask is how much more of a gain could be realized in an engine that completely stopped the dead cylinders?

Decoupling the valvetrain is one thing - decoupling 2 cylinders from the crankshaft is something else entirely.
What's a starter engine on a small displacement engine ?
1 to 2 kW ?
That's enough to get the engine going against its compression - a load the deactivation mechanism avoids.
