There could have been a ton of ways to make the entrance aesthetically pleasing while still making sure it tells the proper story.
Overall, this entire overhaul plan is weak, creatively speaking. Putting characters everywhere is a terrible idea for improving this park.
The park potential's is truly unrealized. I've heard a lot of creative ideas from people on how to overhaul the park, and the best one I've heard would be to make the park revolve around the California dreamers, including Walt himself. Basically, DCA should become a museum of living facts that focuses on the personal stories of these people, as well as celebrate the past, present and future of California. It would be a place where California can be at home and where it can host its guests. The park would also connect itself to Disneyland much better with these changes.
Disney's idea of slapping characters everywhere just shows how they are truly creatively-bankrupt.
