I've found in my own experience that combining to make strong hives in the late fall gives me better success than trying to over winter with a larger quantity of weaker/smaller hives. I'll be combining any hives that are not a full box by themselves by mid/end of October here.
You might try combining some and then using others as side by side nucs in a deep with divider board. Let us know which ones make it best into the spring.
Best of luck to ya
