On the plus side our Typhoon is a late model which shares the Tempest's propeller, canopy and tail section. Also the engine and radiator cowlings should be the same as the Tempest. However just about everything else is different. The Tempest wing is much thinner with a laminar flow section and semi elliptical planform. The gear and flaps are also completely different. The fuselage is longer on the Tempest as they had to move the fuel tanks there due to the thinner wing. The cockpit interior would need a revised 3D model and new art which is a major job in itself.
