If I would build a third theme park, with the parks Universal currently has in mind, I would copy the hell out of Magic Kingdom but better.
First we need a castle, we take the one from The Witcher 3 DLC.
The main street is in the same vain, mediterranean/fantasy.
Then I would give all IP's that are kids related a home in the wheel and spokes park design.
Lets start with Dreamswork:
Madagascar: Tropical setting with the "I like to move it, move it" stage show. Universal already has a boat ride for that IP but half of it doesn't work so it needs to be re-designed. I also take the carousel,
Next to it in Singapore is Shrek and I don't see why not. Sure I take the theming but there will be no movie inside the castle. It will be a dark ride telling a complete new story of the lovable ogre. Sure there will be screens in this ride extending the backdrops or for special effects. And it'll have a song that makes the word 'earworm' obsolete. The ride also goes trough the castle's dining hall (serving Shrek special food). Entering the marketplace you have the 'welcome in Duloc' puppet show.
Do you know How to train your Dragon? You will be after visiting this little village on an island.
The main ride is a flight on the dragons in the same vain as Arthur im konigreich der Minimos. The slow moving hanging coaster that moves in and outside the mountain range. The ride will combine AA's with stunning screens to give beautiful vista's and to simulate fast flight. In the arena there will be an shocking stunningly hour long version of the How to train your Dragon live spectacular show but now it's a musical but uses the puppets. Also tune in for Viking food.
Lets go to Japan to Po's village and visit the temple on the mountain. Sure that mountain could be called Splash mountain but this one tells a heroic and funny story about the panda and it's friends. And yes there will be dumplings in his dad's restaurant to eat.
No let's go to He-man....what you don't know who he is? I get that but when the park is open the new animation shows are running and kids go ape over Skull Castle! It could look something like this and it'll house a walkthrough attraction with real life actors telling an exciting story... or something else.
Trough the dense forest with little streams you you find yourself in front of a grotto. On the other side you have Illumination City and it's huge! It has Gru's street with the home and behind it we can visit his lair/lab where we go on a crazy ride that is a custom wild mouse like (dark)ride but there are more small rides in there for the young and young at hart.
In the city center there is the Sing It Theater. No it's not a show but a trackless 3D dark ride where you and your ride companion each choose an animal. That animal is portrayed in the scene's with the 3 other ones in your cart. And this ride is interactive. No, no guns but microfoons because you have to be on time for auditions, rehearsals and try outs. If you don't like to sing the voice actor will take over but there is no change to win the show.
One part of the city is a Secret Life of Animals ride.
Remember this are just the highlights. There will be a park wide parade, nighttime parade and a castle show.
