Have you also accounted for the increase of size of the two "Mustang" fuselages? 'Cause the Twin Mustang was not just simply two P-51'a slapped together. The fuselage sections were actually of an entirely new design that just resembled the old Mustang.

Mustang P-51D:
Length: 9.83 m
Height: 4.17 m

Mustang P-51H:
Length: 10.16 m
Height: 3.38 m

Twin Mustang:
Length: 12.93 m
Height: 4.22 m

So i guess some stretching is necessary - the Twin should be 3m longer than the D we have in-game!
