This started with me thinking about what an upgraded late-war Hawker Hurricane might look like, but after doing some research it seemed that a significantly upgraded Hurricane would cease to be a Hurricane. Instead I turned the clock back and began thinking about what might have happened if Sydney Camm took a slightly different and more modern approach to the original design - primarily involving a thinner wing, all metal fuselage and minor shape changes (including a longer nose with the cockpit set further back to make up for less room in the wing for fuel).
