Would a 75-77mm ring still make a perfectly circular compression seal in a 74mm bore if it were made gapless down to 74mm?

It's worth a shot, but I don't think it will be easy to accurately remove 0.6mm from each side of the ring by hand. I wouldn't try for the angle, just a straight step. And you probably wouldn't want chrome-plated rings like the OE Zuk/Metro top rings.
I'm getting more and more tempted to reuse my old XFi compression rings with new oil rings. The gaps meet the standards for reusing in the service manual.
