My thought is that you're going to encounter binding anytime you 'push.'
This setup will be great for tension loads,but in compression,unless you had a mirror-image push-pull cable (as in an outboard motor steering system) it will tend to bind up inside the sheath.
In HVAC,rooftop package AC units have an outside air damper which is controlled by an electric motor and bell-crank which can rotate in either direction to modulate the airflow.
