Has anyone bored a WBX cylinder to oversize?

I have a basket case engine - (my first engine which  melted a hole in a
piston and scored the cylinder barrel) - and would like to begin a
rebuild.

I have three good cylinder barrels and would like to get a fourth --- IF
I cna find a good used one that is in tolerance. I would like to bore
them about 1mm oversize. Anyone have any ideas about what problems with
piston size and rings mating that might occur. Any recommendations? This
would be the beginning step for me to Lilley-ize an engine (where does
the royalty fee go?)  -[;<)>

Thanks for the input.
