You have a lot of good ideas i hope anet is listening :) There's just so much that could have been done with the underground of this map that wasn't. Though i could see adding mini games or the dps golem and other things to an area like this.Further Exploration 3WSH - gets underground caverns through the mine area and some sand dune covered buildings open up and become livable. Duplicate merchants for the lower levels and even those glyph karma tools added there and a way point. There could even be an underground lake or lagoon with some deep water bits for skimmer races that players could design. (the other 2 halls both have deep water) Gilded Hollow could get more home like structures on the upper 3rd and 4rth levels of the hall, a WP could be there or on the roof and a the other things mentioned above, dps golems, mini games, karma glyph tools merchant. They could even add things deep down below the water level SEA CAVES - enter thru the water and go back up, plenty of room for zoning down there.Lost Precipice could have some of the lower water level area buildings cut back further into the rock and/or some other buildings added in rock faces that are away from other things for zoning.
