I agree with your general approach. But the details about how you get there are critical. Your turbo's boost must not outflow the methanol's ability to suppress detonation, or your engine will quickly get ruined. A slightly larger turbo (with slightly more lag) allows you to run a bit less boost, thereby requiring less net octane. If you were willing to run pure race fuel, it wouldn't be as much of a concern.
