Cool Dungeon Ideas

Since they are doing Crystal Tower which is an awesome reference to FFIII, Don't you think It would be cool to implement the 4 crystal dungeons from FFI? Think about it, Traversing through a cave fighting hill gigas and the vampire to reach lich, going to the sunken temple to fight Kraken, Decending through Mt. Glug to fight Marilith, and facing the Purle dragon before ascending into the sky to face off with Tiamat. Not gonna lie I would fanboy shriek so hard. And the bosses are not exact copies which could make the do-able. I would say Chaos and Garland but they are too important to be brought back. What do you guys think and what would you like to see or just think is a cool idea in general?
