Well, I don't know if this answers the question... but why not create an inside version or something of the Chocobo Stables found in each city. They all usually have a blocked off door or something behind them.

Why not have the option, when you reach the entrance point that crosses into each city to be able to select Dismount or Enter Stables to interact with other players Chocobos, which would ALSO pave the way as a future area for breeding, raising, and feeding of Chocobos and other Chocobo raising players, similar to FF XI's stables.
