I think an additional X8 could be introduced, operating with the X7 to provide a service half-hourly between Peterlee and Wingate, then the X8 would extend to Bishop Auckland via Fishburn and Ferryhill.
Even though GNE tried a bus between Sunderland and Bishop Auckland with the X20... i wonder if a re-route; like yours could work.
