In another thread regarding the He-100, I suggested that the real thing Germany lacked in the BoB was not a second plane similar (or even slightly superior) to the Bf-109, but effective long range escort fighters equal to the Spit and Hurri and a real long range strategic bomber. I threw out the Fw-187 and the A6M Zero (!) for the first need and one of the Ural Bomber designs (Ju-89 or Do-19) for the second.
What other planes available in 1940 might have been available to the Luftwaffe to address these needs? You are free to consider any Axis plane (or Soviet - this was the time the USSR and Germany were still linked by the non-aggression pact). More critically, would any of these plane really make a difference given that the Germans probably lost the BoB as much a result of poor tactics and preparation rather than poor combat capability of their planes.
