Use the Japan crush of India coupled with a couple house rules:
1 - You cannot build industrial complexes, PERIOD in Africa or Europe. (Lets you build in the Pacific. Ends the risk of 40 American Strat bombers in Norway crushing everything at will.)
2 - Germany gets 9 IPC to spend as they see fit before the start of the game; Italy gets 6 IPC. (Let them talk you down to 6 for Germany, 3 for Italy.)
That should evenup the odds a bit.
