That’s gonna be a challenge. Most of the time I see zone 4 listed as the coldest zone they can survive. You may want to look at some of the techniques people use for overwintering citrus in cold climates to try and keep your saplings alive.
Also if you haven’t already you might want to look into service berries as a fruit tree you could grow in your climate. Some species are hearty to zone 2, so with your 2b zone they should be happy in your climate.
Saskatoons, Alberta native species of Strawberry, Honeyberry shrubs, and two Evan’s Cherry trees are what I have for fruit so far in my backyard. I plan to add short row of Sea Buckthorn too once my end of life cherry tree dies, I think this will be its last year, I’m amazed it managed to produce fruit at all this year given how haggard the poor old bastard is lol.
Burlap probably doesn’t cut it for Pawpaw experiment/challenge. Greenhouse build long term.
