Oddly enough, I placed the Haunted Mansion in Adventureland in a mock-proposal I created for the Imagineer forum! However, mine is NOTHING like the jungle-themed HM planned for Hong Kong Disneyland. More specifically, the Haunted Mansion in my proposed Disney theme park is actually in Carribean Plaza (part of Adventureland), which I themed to a Carribean colonial settlement, along with elements of Disneyland's New Orleans Square; primarily seen in architecture (much of the architecture of New Orleans is in fact rooted in the Carribean), shops, and restaurants (Tokyo Disneyland's Carribean Plaza in their Adventureland has the exact same theming and approach as mine). WDW's Carribean Plaza has more of a Carribean fort-like design/theme to it. In other words, including the Haunted Mansion in Adventureland's Carribean Plaza is also a way of incorporating elements of New Orleans Square into my park, as well as finding a new land to place HM in! As for the design of my HM, the building itself would look similar to Disneyland's HM, but more ghoulish looking (ie: gargoyles on the building, etc.).
I also have an area in my MK park that uses elements of Liberty Square at WDW's Magic Kingdom, called Liberty Street, which is a short road off of Main Street with a group of Liberty Square-like shops and restuarants themed around the Hall of Presidents. In fact, the idea for Liberty Street came from Walt Disney himself, which he planned for Disneyland in 1956! However, Liberty Street never was built, and eventually evolved into Liberty Square at WDW's Magic Kingdom!
