I haven't heard of those. In order to drive up the CR with a flat piston, you'd have to run the piston into the head, and have the combustion chamber machined out to accomodate it.

I don't see a reason for that, other than combustion wave travel. Valve to piston contact would be a greater issue because the valve would be at angle. You wouldn't be able to run it with very aggressive camshafts.
