It would most likely be the same route number all day, every day, like how the Sunday journeys currently interwork with the 50 at Durham. Perhaps a similar scenario could be adopted like in pervious where I think it was the 35A that ran from Sunderland to Houghton-le-Spring on an evening and would then continue to South Hetton? as the X35 (and subsequent numbers since) as the same bus.

Doubt the 20 would continue to run to Langley Park at night given it's been taken off the registration. X20 return is questionable as the 20A is still on the registration, unless the X20 would exist in some other form to previously.
