Then go along the A66 to Darlington from there...Not sure about timing though, could that be achieved around the 60 minute mark?
If this suggestion started at Peterlee Bus Station and served the same stops as the X9 until it reaches the slip road then follows the X10 route to Stockton which would take 33 mins then possibly run via the A66 then possibly run via Great Burdon and Haughton Road and past Darlington College or via the old OK1 route the full journey time between Peterlee and Darlington would take about 56/57 minutes which is a bit tight and gives not much layover time in Darlington.
You could maybe have it continue through to Sunderland via the same route as the Arriva X21 and would provide two GNE buses from Peterlee and Sunderland an hour.
Timings are based on the X9/X10 and the old summer only Arriva service X61.
