What I would like to see is to remove the hat and completely re-do the front of the Chinese Theater to make it a Disney landmark - not a copy of something somewhere else. The Chinese Theater is cool, but it is not a Disney original design as is The Castle, Spaceship Earth and the Tree of Life. The Hat was meant to be temporary and is only a pin station which is easily the lamest icon of all of the parks. The Castle is - well a Castle and you can eat inside. SSE is an awesome piece of Architecture with a ride in side. Tree of Life is a work of art and also has an attraction inside. The Hat is a cheap after thought that was supposed to be temporary.
With the Hollywood name coming to the studios, I would imagine they could come up with a great central icon that takes the place of the Chinese Theater facade and the Hat. I am sure the likelyhood is very low, but one can hope!
