By flaps and everything else you wrote, I assume you mean ailerons, elevators and rudder instead of flaps? Flaps are used to give you a steeper descent angle without increasing speed.

Vectored thrust has been used to enhance control, but I don't personally know of any that have strickly vectored thrust as control. It may work on a trainer or high lift wing, but I would add the controls as backup till you find out what its going to do. anything is possible. Its basically how a helicopter moves. It re-vectors the airflow from the rotor disc.
