I wonder what material choice would be good for bushing pin bores in pistons? High strength 7075 aluminum to match thermal expansion with enough wall thickness to maintain press fit? Seems conceivable. I expect you would have to turn these bushings from bar yourself.
You may have to hone the pin bores in the piston after fitting the bushings. I would also include pin oiling grooves or holes in the bushings.
Or, how about this: Float the pin in the rod eye, press fit into the piston pin bores. This might make the fitment a little easier. Backward from normal but could work? Maybe a bad idea... If I tried this I think I would use pin buttons for belt and suspenders approach.
