What does everyone else think about having more themed events or gear focused on previous installments?

Just want to clarify - NO, I am not asking for another Fate based event where Sin pops up and you have to help Tidus and Yuna kill it, but I do think it would be nice to have maybe casual references in future events.

Like friendly monsters from FF9, or an event tied to Knights of the Round where FF7 seasonal gear could be obtainable. Or maybe CT2 gear drops are modeled after character outfits, such as Monk gear based on FF8's Zell outfit.

Thoughts?
