Can you please everyone? Maybe:
If you want separation, you could use the map sets of
Early War:
Bish 31,25,19
Rook, 16,8,1

Knit 27, 44, 50
Rook 7,13,17
Later War:
Knit 53,49,43
Bish 35,30,24

If you want Axis vs. Allies x 2:
You could keep it as is and just add the Axis/Allies ET at the N front and Axis/Allies PT at the E front.
Just let people decide where the bestest fights are..........
