Controlling Gyro via Thrust Vectoring

Hi All,
Does any one or any devs know if the hover PID can be done in the manner where the gyro is controlled by the motor tilt angle?

I have a quad RC flying car which i realised that the thrust vectoring PID needs to be based on the thrust vector angle and not the fan rpm like it’s used in the tailsitters.

In simpler terms, it’s wanting the FC to control 4x mono tailsitters.
