Personally, I think the oversize piston will cause it to be negligibly out of round, but the increase in ring tension would cause more friction and wear the walls faster. So the little it may be out of round, will have more pressure.
Cflanery should use an ta reader all around the cylinder walls when he does a freshen up!

You noted the same concerns I have.
I guess it could be argued that the ring distortion is no different than cylinder wall variation.
