I have met mine yes. One day I was sitting on the bench of Limsa and a random Au'ra came up to me and was emoting me and staring really closely. A few days later the same person started running around only they...looked like me ;p I took it as a compliment that they liked Siena so much to fantasia into a splitting image of her haha. I took a picture of them!
My character :
Didn't get to talk to them sadly though.
