I would suggest you use epoxy to seal the plywood, and I would have edges that acted as a rim for the bottom. I believe you would either need to permanently fixing the plywood to a stand, or doubling up the thickness so you can offset the seams. I think you are at the limit of 12mm glass at that height(about 2.5 times safety factor) unless you will be bracing the top somehow.
