Perhaps a hybrid of P-84 and P-47N bits? I'm thinking canopy and wings from a P-47N, fuselage, landing gear, and tail surfaces from a straight-winged P-84 and possibly adding the dorsal vertical tail fillet of the P-47N. This will take some hybridization of P-47N and P-48 wings, but the root chords are the same and it looks like a reasonably simple bit of surgery at first study. For grins, replace the 8x .50 machine fit with 6x 20mm cannon fit.
