Not sure what would be the point in that route. Whilst being largely unsuitable due to narrow country lanes, there's also a complete lack of bus stops - or places on those roads to serve, for that matter! You'd be lucky if you picked up a single passenger between Washington and Hexham.
The most logical routing for such a service, if there was ever such demand, would be via the Metrocentre, Blaydon, etc. I somehow don't think there'd be much demand... if any...
