I agree that the Earful Tower should move to the park entrance. Similarly to what was done with the Earful Tower at Disney Studios Paris.
In the 80s and 90s, the Earful Tower made perfect sense being on the MGM Backlot because it was still a working studio. A lot of people don't understand that's a huge party of the story as to why the water tower, the park's symbol, is in the back of the park, because like a real working studio, which it was, water towers were on the lot. The Chinese Theatre was a focal point for the Hollywood section of the park, it was never the symbol of the entire park like the Earful Tower was/is.
Now that the working studio concept is dead, and the backlot will more than likely become something else, why not move the tower toward the entrance. It holds no water.
Here's a quick comp I did.
And what the entrance to DSP looks like.
