Yes, the rings can be taken off and if the valves are closed off and the holes are large enough, there shouldn't be much added pumping loss.
I only metioned the hole drilling, because I've seen it done on research engines where somebody had a multicylinder engine and wanted to create a single-cylinder research engine. So I know it can be done. Whether there are better ways of doing it, I don't know.
