This is a very interesting project for me. It might also be interesting to subtract positions from the maximum possible. After you have a minimal encoding where you cannot reduce it any further, then do a calculation to find out how many ways it is possible to have both kings simultaneously in check. You can subtract this count from the total. I think your current board position may be the current record for a hard proof of the floor of possible board permutations. If you can encode them all, there cannot possibly be more board positions than that.
