Good stuff. That Emerald Spire Dungeon *must* materialize some day in PFO, it could be one of the main draws to the game at some point, both from a PvE and PvP perspective.
I realize it's a massive amount of work, but it looks to cool to pass on.
I'd strongly advise:-
* Roguelike elements: Procedural modules per level to mix it up
* Torchbearer survival elements: Half the dungeon should be survival gear as well as monster-hunting
* Career specialization: Dungeoneering as a career
Remember content-heavy = costly and dev-time heavy => proportional returns by the player base on usage/satisfaction which means the above "replayability" and challenge/cost.
