Predictions for job(s) in the next expansion?

[CKNovel]

A few observations:
1. Clearly there are a number of FF4 references implied for Endwalker.
2. Essentially, every job in FF4 will be represented with the inclusion of Sage (Tellah/FuSoYa), save Golbez, a heavy armor-wearing mage.
3. Does anyone else see a striking resemblance of the Law’s Order DRG set to Golbez’s armor?

My current speculation: Mage Knight

So far, Reaper is the first expectation, Templar the second. (Judge the third and we have the best theories)
Golbez indeed fits the armor and possible melee gameplay, he's a mage but also efficient at melee.

But there's problems with this theory:
-What weapon? Golbez shadow dragon would be a big doubt due to how much resources SQEX would need to produce one.
-How is it related to the shirt? Golbez may have cheated death but he's not directly related to it.

I think we are already served with IV reference, the main character is a PLD that comes from DRK, one ally is a dragoon, the travel to the moon... At most we'll get the 4 Fiends but I doubt it'll go further.
