A lot of anecdotal evidence suggests that smaller nuc hives are massively productive coming out of winter. It could be the smaller size helps the bees more easily defend the space and focus on production, or there is just something about the size constraints. That said, I would think splitting your hives, or letting them swarm and catching a good chunk of them, into nucs, then clustering those nucs for the winter (preferably stacked a few nucs high to make use of the chimney effect), would put you in a good place to take advantage of the relatively short foraging season. Once winter is over you split them up to their hive-stands and move them into larger hives when needed.
I've never tried this, and there is also plenty to suggest that bees get on just fine in northern climates under normal beekeeping conditions. But if I was worried about the climate extremes, I might take this nuc approach to overwinter/clustering.
