Probably not. Breaking an interworking pattern will simply create more duties for the same end result.
More drivers working late just for the sake of a bus type wouldnt go down too well. I would guess that the X21/35 evening cycle is probably allocated to the Sapphire rota anyway, so the drivers are still Sapphire spec on the 35 on a night.
