That sounds like a good idea, but kind of messy, where do you dispose of the "used" oil from the tank in the spring? I will keep that in mind for long term storage(years) I once left stabilized fuel in the same Hobbit for 4yrs! It still started up, ran crappy till all that fuel burned out of it. But it still started! I always drain the carb for storage, I also spray some fogging oil into cylender.
