I suppose if you want to find some middle ground between G40.2 and BM, you could give the bombers a first strike like in 1942.2 but also have the fighters A2 D2 but without first strike attacks.
Seems a bit unnecessarily complicated and fixes something which is not broken to my way of thinking. The BM rules are the ones which aren’t broken. Another possibility is to remove or reduce the first strike of the AA gun.
