I'm glad you like the Cortang, the cause of the bigger fuselage is his relation with the wing profile, the wing of the Corsair have a larger profile and the "tail moment" need to be more far. I'm thinking in a Corsair in the European Theatre, as you know, the engine and compressor of the F4U, his propeller, wheels, etc are quietly different, and this factor could be introducing another logistical problem more. I try to minimize all this things and with the parts of my previous "what if" make this Cortang.
