A possible exception could be a low-tech implementation of your titles or achievements in one game affecting the other, kinda like how you had access to buy certain atma in Abyssea, based on prior achievements in Vana'diel. Even if we can't carry our XI characters over to XIV, small benefits, and recognition of certain accomplishments like acquiring a Relic or Empyrean weapon, or defeating AV or PW might entice more XI player to give XIV a whirl who haven't yet.
Lore Perspective you could do like WoTG and do it as the future if they really wanted.

As for bonus' they could do it like a trait (I assume FFXIV has them) and possibly grant bonus' like Increased EXP, Skill Up(if in it) and so on.
