Just thinking here, if the 131 and 706/707 won't be replaced, I wonder if the Solos could be used on a variation of the 17?

So if it was split like has been rumoured, then Solos could be used from Rosehill/Wallsend to Cramlington as I don't think this service needs a full size bus so they could be used on there, and this would allow for dual door B10s to be withdrawn.
