I wouldn't mind elemental resistances, but the way BLM and Thaumaturge is set-up in this game is terrible for it, and I doubt they're gonna rework that job.

In FFXI, elemental resistances worked because BLM's had access to the 6 elemental spells and so always had tools. It's not the case in FFXIV, obviously, and blizzard/fire being their direct dmg dealing tools...I'd love if it was more of a classic BLM, but they won't make it that way, that ship has sailed. If we can't even get them to make Egi's slightly bigger with more details, this seems like a lost cause unfortunately.

Some of the other things though would be easily implemented. I still don't know why cure doesn't dmg undead. =/ C'mon, now.
