I know repainting wise it wouldn't make much sense but GNE have known to do stuff like this before.
Wonder if 6331 - 6333 might actually be the ones that will end up for the 21 to keep the batch together. You could then repaint either 6376/6377 into the X45/X46 and/or X1 X Lines.
It means you'd have the X1, X45 and X46 all running around with the new Streetdecks, then the X30, X31, X70, X71 and X72 all running with the new Enviro's keeping the oldest Streetdecks 6301 - 6307 as spares across the 3 depots.
