Seestar S50 flange for an external bearing

There's a lot of interest in running the Seestar S50 in equatorial mount, but there have been concerns in online groups about too much stress on the azimuth bearing, the bearing at the bottom of the base. While I don't share this concern, I was thinking of ways to set up an external bearing to take load off the internal bearing. Specifically this would take axial thrust off the internal bearing if an external bearing was firmly mounted to roll on the outside of this flange. Please feel free to modify or adjust this, as it's totally a work in progress.
