It would also cause a serious ruffle in Stagecoach's feathers by competing directly with arguably their most profitable service on Teesside!
Given that and the fact Stagecoach park up a few double deckers during the day between schools, Arriva likely assessed that the retaliation from Stagecoach using these spare 'off peak' buses would have the potential to hurt them more than any benefit gained from linking down to Middlesbrough.
That is why I suspect it hasn't been done as of yet.
