Can't see the X85 doing Blaydon and Metrocentre because the 10 already does, but it would allow direct travel from Denton Burn/Fenham to Blaydon/Metrocentre without going into town, as well as being a quick, direct route to Hexham. I hope the X84 survives for Heddon & Throckley and wherever else. Serving Central Station could be useful.
Would it be possible to run the X85 through Ponteland and Kingston Park into town instead of Denton Burn/Fenham/Benwell or would that add too much time on? 74A used to do Ponteland & Kingston Park between Hexham and Newcastle.
