Disney princesses as villains

So little backstory we are using a world I made up and in it many generations ago the dragons of the world were banished both good and evil(think dragonlance in a way). The group started by being on a boat that was captured and imprisioned in a wizards that was using people they captured to return the dragons through transmutation. When the group broke out they found and killed a Baaz(dragonlance campaign. When dies turns to stone) before escaping into the wild. This was the first step in many different ways the evil group has been trying to get dragons back in the world.



There are a few Disney esque characters that are apart of the organization that is trying to bring back the dragons in the world for villainous reasons. They are known as the Sisters of Silence.
Few of the princesses used are:

Beauty and the Beast - archmage NPC and a werebear.

Snow White - vampire

Sleeping Beauty - mummy

Moana - sea hag

Elsa - Medusa

Going to start by using the monster stats of the ones I listed and customize them each to be close to how they are in the Grimm fairy tales.
