I also highly doubt Arriva would purchase the E400MMC Scania since it doesn't operate the type anywhere in the UK currently & is considerably more expensive than the integral product.

That was due to newer Volvo B5LHs being swapped with them and they had no choice. 

X93 is an interesting one though. Perhaps the integral E400MMC coupled with a ZF box would be fine. Also bearing in mind that the only reason the NK57 XXX series (7501 etc) were awful was due to their previous neglect.
