I'm not an expert, but I grow various kinds of trees and study from others who grow them successfully.
My only concern would be that you protect the trees from the rabbits with some kind of fencing/barrier, as they will surely nibble on the bark and girdle young trees. One of them escapes the tractor, and it may return to cause tree damage overnight. Deer and other wild animals, if they live in your area could be a bigger concern.
This looks like a huge investment in time, money, and resources. Consider paying some local orchard experts for their time, to give you consultation advice based on experience for what works in your area. Find out if the local colleges organize a club to manage an orchard or botanical garden, with educational opportunities for learning. It can take a team of people to manage a productive orchard, and networking with those who love to take care of the trees properly might be wise.
This looks like a wonderful idea for a project. I support anyone seeking to harmonize nature with wildlife/livestock in a sustainable way. To feast in a protected, shaded orchard of peaches and plants, those rabbits will be living in paradise.
