WHM, her parallel is WHM.

Necromancy was a corruption of White Magic after all, finding its home in Gelmorra and the Palace of the Dead.
The WHM job quests in HW deals with raising the dead, and how this can be corrupted.
Nybeth, the lich necromancer on floor 100, also wields a staff/cane, and came from another world after failing to resurrect his own love interest.
All in all, every single WoL in Heroes Gauntlet is a representative of an alternate job, from one of our existing jobs, so I don't think any of them, even Necro, are meant as any kind of hint or set up for future jobs. It would be weird, if they're presented now as a set up for a future job, and then we end up playing that job.
You'd be battling that Necromancer boss... as a Necromancer... it would just be a weird clash of ideas.
If anything, the three bosses are likely meant to show the implementation on these often requested jobs, because they don't intend to ever actually make them real jobs.
Anything 'Soul Mage' related would be covered by Arcanist.
SMN creates aetherial simulacrums to fight with and SCH is literally giving agency or 'a soul' to it's aetherial simulacrums, or rather using one with it's own soul.
BLM is our 'Dark Mage'. It's entire job quest line is about summoning Voidsent. It's signature moves, Foul, Xenoglossy, Despair, are dark-related.
Our 'dark mage' enemies, the Ascians, capitalise on Fire, Ice and Lightning magic.
The 'thematic space' or room left for casters should include Geomancy (earth, wind and water spells) or Time Magic (would need to steal Gravity from AST though).
There's plenty of Groundwork for Geomancy via the Four Lords quest line, so not much more to say on that.
Time Mage could be built upon Gaia, and could sort of provide more of a dark slant to it if that's what you want, but it's not that overt.
The other alternative is an Omnyoji, the Geomancy counterpart that deals with status magic and blood magic. That could fulfil the Geomancy slot as well as ticking the 'dark mage' box. It would probably mean stripping SMN of some of it's DoTs though.
