In the context of FFXIV the 'Return to Ivalice' raid is going to be actually based on an "old Garlean legend", emphasis on legend, so to me that means we're going to end up with something like the Minstrel's Ballad on a raid scale, in other words, someone will tell the story of it to the player's character and their imagination does the rest (hence we wouldn't actually be going to Ivalice in reality, merely imagining it).
It would easily fit within the lore without any changes and still satisfy the "Ivalice and Hydaelyn are separate worlds" rule Yoshi has set in the past. Either way, we'll find out soon enough. :)
