I think the P-47M would be an easy addition. Its slightly faster than the "N" but requires no 3D art changes. Just the FM changes. It has no A2G capability but would be a nice USAAF perk plane in the 56th FG's grey/green camo.
There were substantial differences between the the P-47N and all previous Jugs. Aside from the 2,800 hp C series R-2800 engine, the wing structure was significantly changed. They didn't simply "clip" the wings. A 22" section was added between the fuselage and the pre-existing wingroot. These new sections contained added fuel tankage. The landing gear was moved further outboard, widening the track (actually adding to ground stability). Likewise the guns were moved further outboard and were more difficult to harmonize. Wing tips were partially squared and new ailerons were designed. Weight increased substantially, with maximum takeoff weight exceeding 21,000 pounds. Roll rate improved some, but overall agility suffered. CLimb rate was no better than that of early P-47C type (pre-paddle blade prop). Level speed was higher, simply due to the increase in power, but acceleration wasn't as good as the D-30 and D-40 series. External load remained unchanged, the increase in range was strictly a result of increased internal fuel capacity.
I see no advantage in adding the P-47N, its general performance is not any better than the P-47D-30, except for a minor increase in speed at altitude.
On the other hand, the P-47M WOULD be a significant improvement.
While P-47Ms were delivered without underwing pylons, they had the hardpoints and all wiring in place. Shortly after entering service with the 56th FG, the cover plates were removed and pylons were installed (see photo below). Remember, the 56th used the P-47M for escort duty. It would be the fastest prop fighter in the plane set by a substantial margin above 25,000 feet.
