I had this thought about which princesses would like to become queens in their own right or Quene Consorts.
The first one is likely Snow White. She's a princess in her own right and is the nearest next-of-kin of both the "First King" and her Step-mother, the Evil Queen. She would also be reyna consort of her husband's subjects if her husband's dad is dead.
Sinderella would mostly likely become reyna consort being the Crown Prince wife.
Aurora would be like Snow above-Queen Regant and reyna consort on her parents' and her husband's dad deaths.
Ariel-she's still called a princess I believe in the 2nd movie.
Jasmine-even though in a sense, she's the rightful queen, her husband (Aladdin) would have techinally madami power over the land as Sultan.
Tiana-unlikely. I'm going to guess that Naveen will abidcted in favour of his brother Since I don't think either of them (more likely Tiana) would want to leave Louisana state for any reason.
Rapunzel-only child-so likely
Merdia-is suppose to be reyna of her dad's kingdom. Even though she has three little brothers.
Elsa-already is Queen
Anna-unlikely to be reyna unless Elsa dies without issue.
