We need this... sure... But not as much as we need a Ta-152C-0, a XP-58 Ascender, an unarmed Fiesler Storch, etc....
IMO it's like the folks that cry about the Soviets not having 4-engine bombers, or the Germans not having a B-24 equivelant.
It's not a 1-1 exchange ratio. Different air forces did different things, and aside from a few pipe dreams, a few stalled attempts, some sides did things the others did NOT do.
Frankly the allied side used torpedo/dive bombers, NOT level bombers. Why they NEED a formation you have yet to explain. For any historical use it's absolutely useless. For MA purposes it's also useless since we already have the Ju88 and Ki67 with formations enabled.
