Suggestion: Future storylines/expansions/scenarios set in Eorzea's past

[Enkidoh]

Personally I don't think it would ever happen, at least, as far as restoring how 1.0 depicted Eorzea - the whole reason we actually had the Calamity gameplay wise in the first place was to explain why the badly-designed 1.0 zones were replaced with ARR's new zones (as existing players were just transferred into ARR), so if a hypothetical time-travel expansion ever occurs in the game.... the version of the past you will visit, will not be the version of Eorzea 1.0 players experienced, but palette swapped versions of ARR's current zones, like how the past was handled in FFXI's Wings of the Goddess expansion. Even 1.0's storyline has been retconned by ARR - half of what 1.0 players experienced is no longer even canon or simply ignored.

Also as WotG showed all too well, when you start adding time travel to a MMO's storyline you start adding contradictions into the whole narrative - as mentioned the Calamity occured for a reason and to suddennly go back to the past gives the expectation "we can change history and stop this from ever occurring!" Uh, no, you can't.

Because ARR's whole existence required the Calamity, that was it's whole purpose. Meta wise it was specifically to wreck Eorzea so that the zones could be redesigned - to kill off 1.0 and to send it off with a bang. 1.0 is gone and is never coming back.

Really, we have a whole world in the present still to explore, let the past stay passed, instead having the Echo show past events as they happened. Time travel just overcomplicates things.
