Time to Uncork that '55 Metzner?

My Metzner Starlight (60A) vintage turntable has a glued on cork platter mat. It’s lovely and in pristine shape, however, in refurbishing this table for modern times, I’m considering stripping it off and gluing on a rubber mat.

Does this make sonic sense?

One thing to consider is that this 6 lb. platter rings like a bell. I’ve already affixed an automotive V-belt around the platter’s circumference (picture in My System) which has stunted the ringing by about half. Does the cork serve a purpose in isolating platter ringing from the record and therefore the stylus?

Thanks for your thoughts.
