Luna and celestia swapped roles, and cutie marks how do you think it would play out with tia being sent to the moon instead and luna is the princess of canterlot etc.
Only roles? So... that would mean Luna would still have the same personality? Ehm... No, I feel it would be somewhat the same. They're only slightly different in personality, at the base. The only reason it seems Celestia is more matured, in my opinion, is simply that she's had infinitely more time to practice. You know, what with all that her NOT being on the moon... Also, both of them are princesses of Canterlot?
I don't think there'd be alot of difference, considering raising the sun or the moon is just about the same. Unless size is an issue for some reason.
I'd say Luna would be a little more reserved. Whenever a disturbance occured, she'd plan it out deeply and play things more defensive. I dunno, it's hard to say when you've read too much Fan-fic's that alter you're outlook on Luna.
Are you talking about the alternate timeline "Solar Flare" scenario, where Celestia gets corrupted instead of Luna?
