My opinion - regearing is a better idea than cylinder deletes.

As I understand it, frictional force goes up with higher RPM, so friction increases in a non-linear way, and a 2 cylinder running at 4000rpm would have greater total frictional losses than a 4 cylinder at 2000rpm. If you can drive the car in the same gears as before with half of the pistons removed, great, but if you find yourself upshifting to make power where you wouldn't have previously that's counterproductive.
