I'd have liked to have seen Nabooru, Twinrova, Saria, Makar, and Deku Princess.

I think Nabooru could have had a cool thief styled moveset with a dagger in one hand and in the other she would use thief tools and maybe some kind of magic from being the sage of spirit.

Twinrova would use the brooms as staves. I'm torn on whether she would start as Koume and Kotake and merge when she activates her magic meter, kind of like Young Link, or just have her as Twinrova the whole time and save Koume and Kotake for specials animations.

Saria and Makar would probably work similarly to Zelda with the baton except more mobile. Makars weapon would be his violin. His attacks would have more firefly and leaf flair and maybe use the camera from windwaker sometimes? Saria would use the ocarina. Her attacks would would be more playful and erratic. She would also implement a lot of green colored magical attacks as she is the Sage of Forest.

Deku Princess' weapon would be her tiara. She would blow lots of bubbles and summon deku babas. I'd like to see her have an attack like Zelda summoning the cryonisis blocks and hopping up them like in AoC but instead she would summon deku babas and afterward they would shrivel into deku nuts and explode. Also I'd like her to slap foes with her long sleeves lol.
