I'd suggest that points to the fuel economy not being significantly worse, as there's not a chance in hell First (of all companies) are throwing away that much money if they can help it.
Capacity wise I'm not sure on the exact numbers of the X66 Streetlites, but the B7s would be a small increase regardless - especially in terms of forward facing seating.
All that said, it would be a strange one to go from branded Streetlites to older, second hand B7RLEs (unless it's part of a bigger plan). Personally any move which sees B7s replace Streetlites would be a smart one, they're absolutely fantastic.
Maybe they can be converted to euro 6, and maybe as a result they're more suited to Gateshead area than EYMS. Who knows.
