Just that. Having seen the fuselage frame of a Hurricane up close and in the nude, I don't think that bolting a radial of sufficent power to that would be something that Hawker would have considered. I know that the Tempest did something similar but the Tempest has a wider fuselage (if my memory isn't playing tricks). On a model, those differences are in the millimeter range and easily blended with putty and sanded down. It doesn't work like that on the full scale versions.
Edited to add.... I do like the tribute to the Dutch squadrons in the RAF, including the 'Princess Beatrix' name.
