So technically you can have a time-themed job so long as it remains thematically, mechanically and visually different from Astrologian, which isn't that hard since Astrologian's primary theme is stars and space first and foremost. Also, it wouldn't even be the first time it's happened since Bravely Second had both Astrologian and Time Mage.

The only real issue is that due to itemization designs brought on with 4.0 adjustments, any tank that is not strength-based is impossible to make unless they manage to un-shoot themselves in both feet by reverting tanks back to vitality-based damage, removing strength from Fending accessories, readjusting every single tank ability, and permanently removing main-stat materia to ensure that tanks aren't gaining the materia system like they did with late Heavensward--all of which would be incredibly unlikely to happen just because it's easier to keep the current itemization as-is for the sake of balance adjustments. While I understand that this concept was made pre-Stormblood, it does stick out pretty badly now given how tanks have changed since then.

Aside from that, this is still one of the better time-themed job concepts I've seen. I'd recommend looking more to previous incarnations of Time Mage though, especially that Time Battlemage from XII since it wears heavy armor.
