How feasible is it to use the X-36 airframe for a manned fighter?

Supposing one aircraft manufacturer wants to create a light weight, low-observable aircraft. How feasible is using a design based on the X-36, perhaps enlargening it, as the aircraft itself sports a false cockpit (unlike other UCAVs), has a fueselage similar to that of other 5th generation fighters. It’s only difference is that it lacks vertical stabilizers and has canards..something most 5th generation designs lack.
