In theory it should work ... I have not tried but seems like a good idea.
Maybe 1 period on 1 off is not good, because rotor have big inertia. Maybe it will be better to take, eg 5 period ON, 5 period OFF instead of 1 cycle, on 1 cycle off.
For the driver motor you can use zero crossing opto triac driver, and triac eg MCO3042, and BTA10 or similar.
And you must have RC snubber network on triac, because motor is inductive load.
