You would hope Arriva will take the opportunity to rationalise everything really. They could have quite a streamlined operation going. 

If they got an order of 8-10 MMC's for the X10/X11, displaying the MAX Pulsars to Durham to replace the ALX400's then you could have the following:

Blyth
X7/X8/X9 - DB300's 
X10/X11 - MMC's
306/308 - DB300's 
51/52/53/54/55 - Streetlites 

Ashington
X14/15/18/20 - MMC's
X21/22 - MMC's 
1/2 - Pulsars
43/44/45 - E400's
35 - E400's 
57/57A - Solo's
553 - Solo's
555 - Solo's
685 - Pulsars

This of course assumes that no other services get binned. If there wasn't room at Blyth, you could even move the X10/11 to Ashington with the other MMC services (which I swear was rumoured at one point). That way you're keeping common fleets together. You'd need 1579/80 from Durham to have enough Streetlites, and admittedly you'd probs also have to have E400's as spares at Blyth (tho ideally you'd get 7618/19/26/27 back from Yorkshire in exchange for 7557/8/60/62 though that's probably not that likely - 7609/10 would also be displaced back to Blyth from the Whitby Park and Ride).

If they really had the funds they could get 20 MMC's for the 306-308. Then 10 DB300's could go on the 43/44/45 displacing the 57 plate Enviro's (7501-7507/9 + 7522) to Durham to replace the 55-reg ALX's. The 10 MAX Pulsars could be used for other displacements (Centro's perhaps)
