Admittedly settling for less, a more realistic possibility would be to find a Yamaha YBB-321 (top action) in really beat-up condition on ebay. The bore size of that instrument is only a little smaller than your ideal. Of course, the vintage and the origin are big compromises.
The best of luck to you.
