Not to be a downer on this idea, but the idea of being able to have a personal moogle that pops up randomly, that everyone has thus having many moogles pop up randomly sounds a bit impossible and a lag magnet (if I understood the concept correctly, if I didn't ignore!)

What if there was a moogle mail station you could visit to drop off and pick up your mail? I would love a mail service of some kind in this game. :|
