I decided I would try to use the Dwarven Forge Dungeon Tile Mapper to make it. Well, at least the dungeon-y parts, not the cavern-y parts.
My map is here.
I took some liberties. :)
Here's a list of all the tiles you'd need to build it --
|5||Curved Half Floor|
|4||Narrow Freestanding Wall|
|1||Pile of Treasure|
|1||Secret Door With Floor|
Even though I have 5 sets, I don't think I have enough. :)
