I can't see why you'd have an N50, when there is not enough justification to run it out of Durham after 6pm? It only runs between Chester-le-Street and Shields on an evening, because it is secured.
X1/10/27... you may be able to stick a later run or two in (like they have done with the X1 recently), but I can't see them becoming a night bus anytime soon.
Your best bet are ironically the two you've missed off, i.e. an extension to an already established N21/N56 - or out of the town and right through Gateshead to be specific. I can't see there being much demand beyond Wrekenton or Harlow Green...
I reckon they all could be viable in some way, I would think a lot of people would use taxis across of these areas, so why not offer an extra run or two after midnight, obviously quite a few use the N21/N56 otherwise they'd not of lasted as long as they have, no reason why any of the above couldn't work.
