Axis&Allies is a simulation at a Macro level.
Unit movement ranges, territory boards, are more strategical in their relationship to each other rather than on a true scale of distance/movement capability.
You are trying to inflict squadron level restrictions on units that are conceptual in size (i.e. what does one ftr REALLY represent?) It is most certainly NOT one plane.
While the idea you pose is great, it is for games played at a small unit level, not for Axis & Allies, IMHO.
