I still think Playable Moogles would be fantastic, but if absolutely nothing else, what if they were limited to "Tradeskill-Jobs", and could freely port between cities? It would make them fantastic little Alt-characters, and would fill the void of being able to "play" as a Moogle, without it necessarily impacting the rest of the game. Maybe if they were really well-received, they could continue expanding their customization-options, until eventually becoming fully-playable?
