I doubt we'd ever see the StreetDecks on Castles Express replaced with Volvo B9s. There's no massive need for them to be replaced, either. The allocation of anything besides a StreetDeck has become much more uncommon following the addition of 6332 to the fleet.

They have ups and downs with the StreetDecks at Crook, but they're still some of the most reliable buses in the fleet (despite what is suggested by enthusiasts). The only trouble is when one goes down, the others bizarrely have a habit of following suit at the same time!

The boards on the Toon Link which can be operated by double-decks are operated by double-decks (OmniDekkas at the moment, but gradually being replaced by Volvo B9s). 6108-13 couldn't replace the OmniCitys on Toon Link if this is what you were suggesting, as the single-deck boards operate at least one journey on the X30 (which operates under a low-bridge in Dunston).

However; if/when the Red Kite services are upgraded again, 6118-21 would be a logical cascade to Percy Main for the DFDS service.
