a few point:
Thief = rogue , then no
Geomancer = conjurer, then no
hunter/ranger = archer, then no.
berserker = warrior, everything in the jobs scream berserker even the wrath system was screaming berserker.

even if they plan to abandon the class system they are still present and are way to similar.

another rDPS gonna be hard, what will be the weapon? bow and gun make sense, plus a rDPS is treated like a support then don't expect it to have a huge dps.

Blue mage risk to be a tank probably with a gunblade (will make sense if you look at the blu of ff10-2 that use a gun for cast spell and look at FF14 lore about the gunblade)
dancer will probably be the next healer too.

instead to see which jobs is possible, try more to list the weapon, it will be easier to see what will be coming next depending of this. like:
- gunblade
- whips
- mace
- hammer
- spear+shield
