I think Lucy is the best candidate for Blue Pegasus if the Mages are in fact scattered in numerous guilds, though from Makarov's tone what I got is that each will go their separate ways, not necessarily in separate guilds. Lucy may go in the CS world so that this solitary year is mere days to her, and also so that she can train. I think that's the more realistic choice.
