Hi Richard, and welcome to permies!
The prevailing wisdom regarding moving fruit trees is to do it when they're dormant. If you're in the Northern Hemisphere, that ship has probably sailed and unless you're willing to wait until winter, then keeping the soil around the roots as intact as possible will give you decent results.
Your plan is good...you probably don't even need to go out that far from the trunk if the trees have only been in the ground for a year, and don't forget that soil is heavy. If you can, lift each root ball out and set it on a big piece of burlap, then gather that up and tie it around the base of the trunk to keep the soil in place. When it's time to plant, you can untie the "bag" after you've set each tree in place and leave the material to rot in the earth.
