Aerodynamically, the late model radial Tempest and Sea Fury were VERY close to one another. Structurally, I would not venture an opinion as I have never seen a Tempest, let alone a Tempest internal structure. The illustrations above are nothing like a Sea Fury structure, though. It would be nice to see a Tempest flying, but it looks like a Sea Fury with a dorsal fin in a lot of ways, at least to me. The Sea Fury structure is pretty straightforward, and they are working on two at Chino now, including one at Fighter Rebuilders, so you can see the structure pretty well.
Externally, the Typhoon was similar, too, but the Typhoon wing was thicker (T/C %) and the Typhoon was never going to go as fast as a Tempest, let alone a Sea Fury, even with the same engine and prop.
