I don't think having the X88 7 Days a week would be viable as there isn't any demand for it during the week, I've been to the MetroCentre a few times in recent weeks and it's been dead. I'd keep it the way it is where it gets hammered on a Saturday/Sunday.
But I would re-instate a link between Washington and the MetroCentre during the week in a different form.
For Example
X2 - Easington Lane - Hetton-le-Hole - Houghton-le-Spring - Fence Houses - Shiney Row - Washington Galleries - Springwell Village - Wrekenton - Gateshead - MetroCentre
