Im consiering taking the other fuselage, bolting it to mine and making
the worlds first two cockpit glider, similar to the two cockpit P51
from late WWII.

This has been done already. In Lithuania, Sportine Aviacija, (aka The
LAK factory) used two L-13 Blanik glider fuselages to make a two
fuselage glider. On the wing between the fuselages was mounted a test
rig into which airfoil sections could be mounted. The idea was to test
airfoils in the real atmosphere.

I was told it flew very poorly and was disasembled after a short time.
