I figured I would throw an idea your way to see if you liked it at all before I went through with it. How about putting the T/C behind the king, instead of in front? The T/C would be at the end of the board with the king immediately in front of it and two or three squares between it and the next piece. Having the king forward gives it more ability to defend itself and putting the T/C behind it prevents an opponent from dropping a piece on that square (with another piece defending that end square so the king can't move backwards and take it). Alternatively, however, you may want to move the king forward without putting the T/C behind it since that would be more conducive to paratroop offenses against the king.
