Thanks everyone! It's nice to know I don't have to lose these beautiful trees.
I was hoping somebody could tell me what is best for the trees' welfare...but that's ridiculous, every tree is different and even if it's not (because it's a clone or grafted), every situation is different.
It sounds like the trees would do equally well dug up or cut down. I read on houzz
https://www.doityourself.com/stry/how-to-transplant-a-serviceberry-tree, you should wrap the roots in damp mulch and wait til autumn to transplant. I have one more day with an excavator...maybe I'll just bite the bullet and move the trees. I hate the feel of tearing roots but I can give them huge new prepped planting sites when I have a machine.
