Got my comment a bit muddled. White (RN,BN) is favored over Black (RB,K) by
the revised rules (each must retain two pieces) -- for essentially the
reasons I gave.
Upgrading the Black Q to RBN would almost balance the game, but the
maximum promotion to RBN for Black vs RN for White would favor Black. A
Black Q = RBN with promotions limited to R, B or N for both sides would
probably come pretty close to a balanced game.
