When OK Travel ran the 684 which, was from Bishop Auckland depot they used to do an in service move to their garage in Bishop Auckland so guess it is possible with some imagination.

Obviously yes driving hours can be a factor however Im pretty sure you can't do say X21 West Auckland, X21 Newcastle, X21 Bishop/West Auckland (pretty sure even Durham would go over it) then run dead to Riverside without running out of driving hours.
