Changi with diagonal pieces

In changi, Korean chess, most of pieces moves orthogonally, but can also move diagonally along palace diagonal lines.
Here i added pieces, wich moves diagonally, but can also moves orthogonally along palace orthogonal lines, wich crosses palace's center.


Pieces, wich already appeared in original changi on diagrams: K - king (general); G - guard; P - pawn; R - rook; C - cannon (here it cannot leap vaos of either color and capture vaos); N - knight; E - elephant. New diagonal pieces: Bishop (B): as FIDE chess bishop, can move as rook along palace center orthogonal lines. Vao (V): as bishop, but must leap over exactly one piece, capturing or not; may move as cannon along palace center orthogonal lines; may not leap over cannon or another vao and can't capture them. Queen (Q): have nothing common with queen from FIDE chess: it moves 1 diagonally or 1 orthogonally along palace center orthogonal lines, may not leave palace. Royal (see below). Advisor (A): as queen, but not royal. Stone general (S): 1 diagonally forward, can move as pawn along palace center orthogonal lines. Do not promote. Name is taken from shogi variants. King and queen can capture opponent's king and queen without moving if there are no pieces between them. Capture opponent's king and queen to win. I have 5 opening setups for this game, choose one you like most. 1st: all normal pieces, plus new diagonal piece: rnegqgenr b--aka--b -cv---vc- pspspspsp --------- --------- PSPSPSPSP -CV---VC- B--AKA--B RNEGQGENR 2nd: same as above, but no queen. 3rd: orthogonal pieces on one half, diagonal pieces on other half. Reverse symmetry is used. rnegqaenb ----k---- -c----v-- p-p-p-s-s --------- --------- S-S-P-P-P --V----C- ----K---- BNEAQGENR 4th: same as above, but no queen. 5th: only diagonal pieces. bnea-aenb ----q---- --v---v-- -s-s-s-s- --------- --------- -S-S-S-S- --V---V-- ----Q---- BNEA-AENB Remember, that all pieces can sometimes move orthogonally, and thus, there is no bound pieces, expect vao, wich moves orthogonally only 2 steps. But, i think, it would be better if one of center rank would be removed (here vaos cannot move orthogonally, but as they don't change colors at all, it's not important): bnea-aenb ----q---- --v---v-- -s-s-s-s- --------- -S-S-S-S- --V---V-- ----Q---- BNEA-AENB Here are more 5 setups, wich also uses "diagonal" knight and elephant pieces. Moa (M): as normal changi knight, but first moves 1 diagonally, when 1 orthogonally. No name piece (L): as elephant, but first moves 2 diagonally, when 1 orthogonally. These setups are same as above, with these expections: first and second setups: moas starts in front of each knight, no name pieces starts in front each elephant. Third and fourth setups: moas replaced knights and no name pieces replaced elephants in half of board with diagonal pieces. Fifth setup: moa replaced all knights, no name pieces replaced all elephants. In all these setups each moa may be optionally replaced with adjecent no name piece before playing.


I need someone's help to calculate values of new pieces to make drawless game rules like in standart changi.
