While I forgot the details, besides originally planned to be fully 2D animated. I decide to list a few idea from the original version of Wish that ended up scrapped.
1.) King Magnifico and Queen Amaya were going to be the first Disney Villain Couple
2.) Asha had more personality and was an apprentice while Star (known as "Starboy") was planned as a magical humanoid figure who is able to shapeshift who was set up as Asha's potential love interest
3.) Valentino actually played a bigger role in the film's plot and actually tolerable. Valentino wouldn't speak until the third act where he help Asha defeat King Magnifico who undergone a Villain Transformation (ala Dragon Maleficent, Giant Ursula, and Jafar's Snake and Genie forms).
There are tons of articles and Youtube videos which delved deeper into Wish's original storyline before it undergone changes during production.
