This strategy is called "picking up pennies in front of a freight train". That being said, I've done it, my own conclusion was that it was better to do it infrequently, and naked, rather then all the time because all the commissions and slippage on all the hedge options killed what little profit there was. I used to do it with Google earnings, those came out on expiration day so the IV on the far oom would still be really high. I never got burned but it made for some sweaty nights.
