Greetings
I think I agree with Kansas City Bob on this issue, especially where you are physically located. Given you get I'm sure a good dose of snow, sustained freezing rain, sleet, snow and harsh winds, I'd be inclined to take any cuttings that you want now, especially if all leaves have dropped and the plant is now dormant. If you prune now, you not only get cuttings to plant later, but your tree is generally smaller and easier to cover if u choose to do so. Having long, exposed branches in your region only sets them up to freeze back.
If you can include some pix of you are trees as they now look, it will give us all more ideas to "assist."
I'll be pruning back my in-ground Hardy Chicago and Celeste soon, and surrounding with a cage filled with maple and oak leaves.
