I think you can make it work!
What are the main disease worries for apples and peaches in your area?
How long do you plan to stay here (affects what you plant possibly maybe you need dwarfs or plants that are precocious and bear fruit sooner also containers speed up precocity and take to moving like a couch)
Definitely all the no spray stuff on here i think you should try and it sounds like pomgranny has had excellent results with pomegranates and there are lots of cold hardy ones available. Like blueberry said you definitely have citrus you could get going but they would need some TLC and extra effort but you would do great putting them in high tunnels or greenhouses. Look at this thread you can really do anything you want to do if you match it with the appropriate effort
