Before I start, I would just like to say I prefer the things that are actually happening to having a Pixar park.
So lets go before World of Color, Toy Story Midway Mania, Silly Symphony Swings, Carsland and The Little Mermaid were build and announced. When DCA was its old self.
If I was the main decision maker for what to do with DCA, I would have honestly gone with a total Pixar park. I would have been abit reluctant to do it, but I would have in the end.
Paradise Pier had concept art to change it to a Toy Story themed Pier. The Orange Stinger was going to be changed into a Claw themed ride with those green aliens. Midway Mania was going to be built, the Zephyr was going to get a Zurgh overlay. Green Army Men were going to take over the Maliboomer. Then Screamin could become a generic Toy Story rollercoaster and the Games of the Boardwark all become Toy Story oriented.
This would have meant that Paradise Pier, Bugs Land and the soon to be announced Carsland would all be Pixar themed. Add in the Pixar Parade and most of the park is Pixar.
This would only leave the Golden State and Hollywood Pictures Backlot left.
If I was the decision maker, I would have turned the Golden State into a UP themed area with Soarin over California replaced with an UP film and also added in some UP characters to Grizzly River Run.
This would leave Hollywood Pictures Backlot, which is abit trickier. I would have replaced Aladdin with the Toy Story Musical, kept Monsters Inc, and replaced Muppetvision 3D with a Incredibles 3D film. Then you have a basic Pixar street, which would be the 'Contemporyland' many people have mentioned on here before.
I just think this would have been more of a guarantee money maker then what they are doing now. Yes, I would much prefer what they are currently doing now to this, but I would have reluctantly done this if I was in charge.
Now before I get flamed to death I know I've missed bits out, like the Tower of Terror and the Pacific Wharf area, but seriously what could you do with them, Pixar wise?
But I think this would have gone well with Disneyland. Having a Disneyland and a Pixarland seems to mix well. Plus it would make an excuse to get Nemo out of the Subs
