You'd need a conductive surface to start with, and the ceramic is
a quite good insulator. The "activation" techniques used to make
plated-through-hole PCBs might work to provide a surface for the
electroplating.

I suspect (don't know for sure) that it is done commercially by
printing a conductive ink onto the ceramic disks and then firing
the disk in a controlled atmosphere (to prevent oxidation).

But, for a one-off, maybe it's possible to use the conductive
stuff you can buy to repair car rear window heaters.. I think auto
supply shops stock that.

Best regards,
