Agreed, the park icon doesn't necessarily need to be visible across the entire park, making it so, can be distracting in other areas of the park. In most of the park's, the main icon serves as the "weenie" as Walt called it, and it's primary task is to draw people toward it. Both the Chinese theater (facade) and Mickey's Sorcerer Hat did a pretty good job of this, whether you liked it or not. If the hat is indeed going away, the question remains of what will replace it, or will they just revert back to the Chinese theater without anything blocking it?
Personally, I think DHS is in need of a mountain for the park. More specifically, I think the studios needs to build a replica of Mount Lee, the hill/mountain that overlooks Hollywood and has the famous HOLLYWOOD letters. I worked up a concept for this last month,
here. I think they could easily do this and make it a facade for the Great Movie Ride like the one for NY Street or San Francisco. Or, they could go all out and build a real-looking mountain to replace Catastrophe Canyon and then put a ride in it.
