With insurance its a series of short term events. Every single year you should evaluate it and decide accordingly whether its worth it. Having, or not having, insurance this year has no effect on next year. Barring seasonal weather (hail happens in the summer, not winter here), there isn't much difference on a daily basis.
Gambling 2 months is a smaller gamble than 12 months, but the risk/reward is the same on a daily basis, unless you point out which 2 months will have the increased premium and then correlate the risk of weather damage for those 2 months. Then it stops being a hypothetical and you can put forward a reason why the risk would be different. For example in January/February where I live there has never been hail, hurricanes, tornados, lightning, wildfires, ice dams (they occur in march/april) or other events. On the flip side pipes tend to freeze if the furnace goes out for more than 2 days, extremely unlikely, so my major risks are down for those 2 months.
If you were to do this long term I would still do it for a single year now then resume when you have a new house. Interrupting it for a year before resuming the high deductible isn't any different than doing it continuously. There's also the caveat; you always need insurance when you can't afford the loss, I don't know if you can/can't pay the high deductible without it being a major problem or a minor inconvenience. When I first owned my home a $6000 deductible would have been huge, now it could be paid easily. Same person and same house but different points in my life.
