I'm thinking this would not be a
good plan. For the piston engines you referred to, I bet they have a way
to control the valves with solenoids so the deactivated pistons aren't producing
compression.
Actually they do have compression. No fuel or fire.

OK, make me look
it up :-) Apparently, they stop the valves from opening, rather than
leaving them open. I couldn't find anything that gave details of exactly
what point in the sequence they stop the valves, so the cylinder could either be
full of air (silly and wasteful of power), empty of air (would cause vacuum that
would be as bad as the compression force), or perhaps somewhere in
between.
Here's the best
article I found, though with annoying ads. Don't forget about those
active controlled engine mounts to smooth out the 3 cylinder operation in
economy mode. Just boggles the mind what they'll do to make improvements
in economy.
