Problem with that is the Bedlington and Morpeth extension.
It could be viable to extend the 53 to Bedlington and truncate the 43 to there too, with them alternating into the newer estates in the area. Perhaps sending one of the routes via Bebside and Bedlington Station to cover the Bebside-Cramlington leg of the X9, with one of the X10/X11 starting up in Bebside instead to maintain the Newcastle link.
