Several issues: 1. 6 piece files are going to require some large mate-in-N scores. IE they will need 16 bits at least, which doubles the size compared to a current 5 piece file where all scores are 8 bits max. 2. another piece multiplies the size by roughly 60. 3. Unknown compression ability. We already have some 6 piece files that are 3+ gigabytes. These are pawnless which have max symmetry. Pawns will increase that significantly.
