Airbus A380 Beluga "what-if"

Imagine the Airbus A-380 being converted to a Beluga transporter. Here is my attempt to create this "what if" beast in 1:144 scale.
The plan is to build a master of the fuselage, then make moulds. As such, I can laminate a light hollow fuselage (epoxy/fiberglass).
A display will then be created of the A-380 Beluga with a A-350 fuselage inside.
