To me it would seem to be easier to create more power in a 4 cylinder when its needed , then it would to deactivate half the cylinders and drag them along, tryin to get a 10% improvement/.This to me has been shown particularly true with fuel injection.The early carbed v8 to v4 conversions got around 26 mpg with dummy pistons in the dead holes. If you don't use dummy pistons then you are dragging the rings along. especially if the valves are disabled, and creating both compression and vacumn situations the other 4 cylinders must fight against. In addition you are carrying a lot of unneccessary weight, that would net you free mileage. In my mind it was tryed and was a waste.
