DGS was more complete than most, but still not complete in the everyday sense of the word because of some missing Luftwaffe aircraft. The 109G-14 and 109K-4 belong there, but both are a poor substitute for a 109G-14/AS, G-6/AS or a 109G-10. Regardless, I'll agree that it's hard to do better than DGS with the planeset we have.
In BoB, not only do we not have the He 111, or the Do-17, but our Ju-88A-4 always subs for an A-1, and our version of the Stuka also missed the battle (We need the Ju 87B).
For early war PTO battles we don't have the Buffalo or the TBD devastator, which fought in the battle of midway, the next FSO.
A Hurricane Mk IIB would be the first Hurricane to go to North Africa, which should be opposed by a 109E-7.
