The propeller feathering can reduce windmilling to considerable extent.
You could, but then you would be generating additional drag. This would most likely require more energy to overcome than the energy generated by the windmilling propeller.
Perhaps you are thinking of the Osprey or some other "tilt-rotor" aircraft. There is also the auto-gyro which works by propelling itself forward with a regular propeller & flies by using the lift of a windmilling main rotor.
Feathering an aircraft propeller involves rotating the blades to a position that significantly reduces drag, typically during engine failure. This helps to minimize the aerodynamic resistance on the aircraft, allowing it to maintain a better glide ratio and improve performance during an emergency descent. Feathering is particularly important in multi-engine aircraft, as it enhances safety and control by preventing asymmetric thrust. Additionally, it protects the propeller from potential damage by reducing windmilling in a failed engine.

How do you build a propeller
A propeller airplane is, simply put, any airplane which uses a propeller for propulsion.
A propeller is a rotating wing.
The spinning shaft from the engine to which the propeller is attached.
The inventor of the propeller is Wallace Turnbull.
Propeller - band - was created in 1980.
Propeller Island was created in 1895.
Hartzell Propeller was created in 1917.
