No. For such a conversion, any modification which makes the plane no longer airworthy can be made (i.e., you can put as much steel struts in there as you'd like, and just remove heavy parts like engines, fuel etc.), and as such requires zero knowledge of aircraft design. In fact, I feel pretty confident designing a steel structure to support this aircraft, having exactly zero experience with aircraft design in my masters mechanical engineering.
For reference, let's quote the scope of this SE site:
- Flying technique, maneuvers, navigation, procedures, etc.
- Air Traffic Control
- Aviation Weather
- Aviation Regulations
- Aerodynamics (related to aircraft)
- Aviation Safety
Oddly enough, I don't even see "aircraft construction/design" in there, which might be a good one to add.
