One might add a one-space orthogonal step to the Knight (Wazir Knight) and
a one-space diagonal step to the Camel (Wizard from Omega Chess), and both
moves to the Wildebeest (Wildebeest plus King). This preserves the symmetry
between the riding and leaping pieces, and now the King is integrated into
it, having the moves which are shared by Queen and Wildebeest.
And the stronger pieces can be seen as a second advantage, if one feels
that the standard pieces are relatively weak for the big board.
