Haymarket would probably be the best place for it to leave from as pretty much all Arriva services in Newcastle leave from Haymarket (the 85, X12 from Eldon Square) although there would be difficulties entering Haymarket Bus Station on a service from the Metrocentre.
Turning left out of Eldon Square and right out of Haymarket (and vice versa) does seem to be the limiting factor. I would suggest that's historical, but I used to wait at Haymarket for the odd service to Low Fell. I suspect it's been tidied up by not having services crossing over.
