KeithGraham:As one of veteran players who has played shogi for more than 35 years, I would agree on your suggestion if a user can choose the traditional pieces or the proposed pieces here on BrainKing.
As to the physical set, I wouldn't think it'd be feasible. Please appreciate the fact that the other side of a playing piece is already used for promotion, except for King and Gold.
