Speaking of design teams; here's a rough listing of how much was made for the Luftwaffe 1939-1945:

I took the liberty of computing the numbers for just 1939-1943 to give an idea of who would have been on top in the timeline resulting in RecruitMonty's mod (1944-45 is an abnormal situation for the purposes of this mod).
Junkers: 18,019 aircraft, of which the majority (53%) is the Ju-88. But they are very diversified, with 2,469 transports (Ju-52,Ju-252,Ju-290,Ju-352) and 3,869 Ju-87 Stukas being built.
Messerschmidt: 17,853 aircraft, of which the majority (76%) are Bf-109s. Remainder of their product line is largely fighters (Bf-110, Me 210, Me 410).
Focke-Wulf: 6,584 aircraft, of which majority (83%) are FW-190 derivatives.
Heinkel: 5,761 aircraft, of which 85% are He-111 bombers.
Dornier: 2,330 aircraft, of which majority (58%) are Do 217 Bombers followed by 20% Do 17.
Henschel: 1,149 aircraft, of which 55% are Hs129 Strafers.
Gotha: 43 aircraft, of which 100% are Go 244 transports.
Likely prospects Post War: The Big Four (Junkers, Messerschmidt, Focke-Wulf and Heinkel) are likely to swallow up smaller competitors as the cost of military aircraft gets bigger and bigger with the coming of the Late Jet Age (1950s), then the first airborne computers (late 1950s, early 1960s).
According to Flying Magazine Sep 1945; it took the US in 1939 about 150,000 engineering man hours to bring a heavy bomber to just beyond prototype stage; but this had been increased to 1.5 million man hours for the B-29 at the same stage of development; so you can see where this is going.
