PWM or stepper motor throttle stop idle control

[andrew_mx83]

Implementing air bypass style idle conrtol will be a PITA with 6 ITBs, is there any reason i cant simply pwm a solenoid to hold the throttle slightly open like used in the carby days?
My factory stepper motor ISCV is nicely packaged with a linear actuator, i could unbolt the bottom half which handles the airflow and simply mount the stepper/actuator to press on my throttle linkage which would be my preferred option
Will this work well enough?

I've often thought of doing the same thing but haven't gotten around to it yet. I think you should go for it and let us know!
