Hello Juan !
Yes, It's possible - just remove (fill) the panel lines of 4 fuel tanks (outboard and leading edge) access doors on the lower wing surface, and remove relative overwing fuel fill ports. The Modelsvit DD kit contains gun parts and spinner for T, spinner and engine exhausts for early M. Canopy/cockpit are located on the same position on DD, M and T, not on D, moreover DD, T and M fuselages were unitized on the real aircrafts.
Brgds, Ivan.
