Details to convert pressed piston pin to full-floating?

If you read around, there is some writing about them wearing/scoring the bores on the sides. Perhaps carbon crud gets embedded in the surfaces and acts as an abrasive.
I am looking at the same thing: press fit pins on floater rods. I have been considering a small set screw from the underside with red Locktite, and perhaps a matching groove in the piston for it to lock into. The pin does not seem to take a lot to hold it in place. I've been wondering what problems (and thus disasters) might come from that approach.

I had hemi pins w/ the right end play knock the old style pin locks out and drag the cyl. wall.Doesn`t happen w/ spiro locks tho. A dragraceing friend that was darn successful tried the buttons on a couple of his race motors, he went w/ spirolocks when the first came out. He said the buttons took too much attention to keep using them. I ran steel , stock chevy rods that were honed out to make full floaters, w/ an 1/8" , chamfered oil hole in the top of those rods, on the street in a 383 sbc, worked fine !
