Chocobo stables, alt characters on the same accout access

I own a single player house and a newly acquired chocobo stable. I have several alt characters I do role play with. I don't have any of the alts in a new FC I joined, since I don't want to flood the new FC with all my characters. I would love it if, since the "alts" are on the same account, a future patch would include their access to chocobo stable for player housing. I hope this is possible but I do understand how busy the Devs are with working on all the new content.
