Theoretical situations are tough to understand, but pyshics are pyshics. No lift (airfoil wings) no flight.
If an aircraft does not have sufficient airflow over the wing surface to produce lift, it will not fly. This is demonstrated by small aircraft landing into a strong headwind....small planes can actaully land flying backwards if the windspeed is greater than the minimum flight speed in still air.
Without data to define the "plane", it's impossible to calculate if the plane could fly based on prop wash over the wings...
Good brainteaser.
