Immersive and deep, or archaic and annoying?

Seconded. All those ideas sound so awesome, ESPECIALLY the elemental weaknesses. That's practically standard for JRPGs.

Unfortunately, we're unlikely to get it. They'd have to completely rebuild the magic system (again!) to introduce elemental weaknesses, because the way it designed now, you can't choose which element to use. THM/BLM? Your main attack spell is Fire, and you'll need to rotate to Blizzard to replenish your MPs. CNJ/WHM? Your main attack spell is Stone II. SMN? I'll admit I don't know enough about the Egis, but you appear to need to select from them based on non-elemental factors and in any case, you only get three of the elements. ACN/SCH? You don't even get elemental spells, so you're not part of the discussion. You can't choose another element because there's no adequate replacement.

Um, actually they do have elemental weaknesses in the combat engine, you can see your own elemental resistances on the character page, and specific items/armor can increase resistance to particular elements as can materia, so the capability is already there. There is no problem with casters only having 3 of the elements each, as long as enemies are neutral to one of their three elements, they will still be doing their base damage as normal, if elemental weaknesses were tweaked into effect, then using fire on Ifrit would produce poorer damage than using ice on him. It all depends on the elemental resistance that each mod is configured with. I see no reason why this could not be patched in with minimal effort (mostly the change of monster stats).

I also think that you can see elemental weaknesses in game, though their effect is minimal right now. I could be wrong in that but my sense is that THM has a much easier time with some enemies than others, and that suggests elemental weakness to their main attacks on some enemies, but not others.
