I did a thread search for "Ivalice" and it didn't turn up any results SO:

The gear from the Ivalice raids. The models are all unique and there are no other gear pieces in the game that look truly similar, let alone can be dyed.

I would love to see the Ivalice alliance raid gear be updated to be dyeable
OR
For a future crafted set to be made with the same models, but with different base coloration, and able to be dyed.

We have seen something similar before. Void Ark (level 60 alliance raid) gear was used as a base for the Nightsteel (Level 70 crafted) gear.
