Well, you are not alone because they converted the Swiss Family Tree House at
Disneyland into the Tarzan Treehouse. It's basically the same except for Tarzan figures in the scenes and the music. The layout is a little different at DL, but it's pretty similar overall. They did this a while back, probably around the time Tarzan came out. I actually kind of prefer the Tarzan version, though I refer to both attractions as "Stairs: The Ride."
