I think it would be a waste of time. You'd have to cut them right back because the remaining damaged roots wouldn't be enough to sustain the tops or prevent rocking in the wind, so you'd lose the height anyway.
With the amount of root damage from mechanical excavation, almost guaranteed to chop through loads of roots, they'd probably die anyway.
and then you'd be a year behind with a new hedge. If you look around the garden you may find some young ones to transplant.
