Disney princesses as Winx fairies

Hello!
I need a help with a personal project of mine. I want to make Disney princesses Basic Winx and Enchantix forms, but I'm strugling with deciding some of the princesses' powers.

Here's what I have so far:

🍎Snow White - Animal Fairy

🥿Cinderella - Time Fairy

🪡Aurora - Fairy of Dreams

🧜‍♀️Ariel - Ocean Melody Fairy/Fairy of songs

🪞Belle - Fairy of Enchantments

💎Jasmine - Fairy of Gemstones

🐲Fa Mulan - Fairy of the Dragon Flame

🪮Rapunzel - Sunlight Fairy/ Fairy of Sun

❤️‍🔥Anna - Fairy of Love

❄️Elsa - Ice Fairy/Fifth Spirit of the Enchanted Forest

🌊Moana - Fairy of Waves

That leaves Tiana, Pocahontas and Merida. I thought of making Pocahontas a Fairy of Nature, since in a movie she is connected to everything around her. For Merida, I wanted to make her Fairy of the Wild. But, these two are kinda similiar to each other and their fields of magic would be overlapping. So what else is there? Merida - Fairy of the Hunt? Doesn't sound very fairy-like, that seems to me more like something a witch would be specialized in. As for Tiana, I have no idea. I really, really don't want to have her be a fairy of amphibians or frogs or a swamp fairy, this doesn't represent her as a person at all, she just happens to transform into a frog, but she isn't a batrachophile. What then? Fairy of Cooking? And what her attacks would be then? Magical Indigestion? I am at a lost with her, she is the hardest to me.

I also thought of making Megara, Kida, Esmeralda and Giselle in this Winx AU, as they are also female Disney characters that I love a lot. Megara would probably have a transition between a witch to a fairy like Mirta, and just like her, Meg would be the Witch, and later the Fairy, of Illusions (as I think it suits her pretty well). Kida would be probably the Fairy of Energy (because Fairy of Crystals would be too much like Jasmine's niche in this au). Esmeralda and Giselle, I have no idea for. But these characters are not my priority here. I need to focus on my main girls first, because I might not even have energy to finish main line up lol.

So any ideas would be a great help.
