Another vote for the tree house for the aforementioned reasons. Although I'm not sure how that would really free up enough space for a new attraction. As for FM not having lines, I agree. And I love it. It's the one ride we know we can usually get on without a long wait. Now, on with my slightly off topic tangent: I understand the park needs people to make money. I understand the park wants rides and attractions that will attract more people, more money. However I don't get why they act like it's not ok unless every single square inch of the park isn't elbow to elbow with people and every ride has 400,000,000,000,000,000,000 people standing in line for it every second of every day of every month of the year. Increasing attendance is fine, to a point. Unless they are going to physically make the square footage (or acreage, whatever you choose to call it) bigger at some point they won't be able to fit any more people in there. One of the reasons I enjoy going is because I know when to go when it usually isn't crowded. If that ever stops and there are no "slow days", at that point I will quit going.
