This has been my logic as well in planting ~200 Black Walnuts since 2014 (and this year, 25 White Oaks) at my lands in the Upper Connecticut River Valley, outside the hardiness zones of both of these species. I figure within my lifetime they'll be comfortable, if they can last to that point.
2014-2015 was the coldest winter ever recorded, and all my "first wave" testing walnuts survived it, so it gave me the green light to plant more over the following years.
The tallest ones now are taller than your oak. (The seedlings cost me 60 cents each at the NH State Nursery.)
Edit: also, I've always done all of my planting in the spring.
