Miyata seat on a Schwinn or Semcycle

I’m just wondering, has anyone had much luck putting a Miyata seat on a Schwinn
or Semcycle deluxe unicycle?

I figure you can either modify the Miyata seat to acomodate a schwinn style seat
post, but loose stability in the process, or drill some holes in a Miyata seat
post, and run a similar risk of loss of stability?

I know I’ve seen Schwinn style frames with Miyata seats out there, I was just
wondering what the good way is to go about arranging such a combination.
