You can play with Pawns promoting to Princes instead of Queens, as they lie on the second rank, as the Shogi Bishop and Shogi Rook do. You can even play with a naive promotion of Bishops to Primates, Rooks to Chatelaines, and Pawns and Knights to Queens. Of course, the Draughts variant is not playable. In Draughts, you must move forward, so there is no opportunity to permanently block. Rithe with capture, the board clears up and the pieces that can move backward cannot cower behind a wall. What defense there is is solved by zugzwang. Your variant fails in that one can move a King into an opponent's corner and blockade him with dropped Men and another King, providing only enough space for tempo moves, with the Men blocking any mandatory capture.
