what you are proposing would not make much sense to me, because using only compass heading will not steer very well. The tiller pilots like st1000 or st2000 will use about half as much power and steer better if you use only the motor with pypilot electronics.
Most of the needed corrections are based on the gyro, and autopilots that don't have this sensor are differentiating it from the compass which gives a poor result. I'm not sure how you will get this data to the st2000 or if it can even accept it, and although the compass HDM output is based on both compass and gyros, there is data loss from not having the gyro reading.
pypilot does output HDM, but not at the full rate it normally runs at since it's intended for display purposes. There is a lag of up to a few hundred milliseconds which will degrade performance slightly as well, especially on a small or light boat.
So doing this you would basically just be using an st2000 as before with , only getting the compass heading from pypilot which may be an improvement but you would still be using an st2000 for the control loops.
I would recommend installing a switch on the motor so you can try both ways hardware, or just leave the st2000 alone and build another actuator for pypilot, but in any case if you get something working let us know, but please don't claim you are using pypilot for anything more than compass input.
