I don't think it will require major changes, COD already has the strat map, it just needs to be enlarged to fullscreen, as an opening screen. players can then allocate units to airfields and set inital orders for early morning first day .. and watch what happens. The british with its central command & radar will have a advantage with the amount and speed of information. As the game plays, details could be saved to a stats file. When 2 enemy units intercept, a battle will begin and the player can zooom into the tactical battle.
Doesn't sound too difficult considering most of the difficult work (great battles / terrain) has already been done (AI might need polishing).
