I'm considering tractor propeller driven flying wing with vertical stabilizer only.
This is an open question seeking feasible approach.
Possible options:
Stability. Change of angle of attack either intentional or by air conditions changes wing lengthwise distribution of lift. Is it manageable for human to safely maintain stability in such conditions and if not - for a computer?
Thrust availability. Approaching landing the forward thrust is minimized, so there should be close to 90° downward thrust line deflection.
Thrust agility. All options are fine except probably EDF. They are pretty responsive but it may be not enough. What about a nozzle limiting the output?
So, is it viable to add enough nose-up moment and stability by vectoring thrust to counter the nose-down moment produced by flap extension, thus allowing the use of flaps to decrease speed and angle of attack at landing?
Thanks in advance.

Possible options:
- hidable EDF at the front
- tilted prop rotor
- collective pitch thrust vectoring (swashplate driven)
- retractable canard fins to divert the thrust down
- your suggestion, please
