KH Based/ Nicktoons Crossover Idea- Interest Check

I know it sounds weird and stupid but I just though, why not. I am a big fan of both Kingdom Hearts and Nicktoons/Nickelodeon (when it was not all tween-ish) and I might have found a way to bring these two together. Please be honest about this and please add any suggestions.
And With that:

Kingdom Hearts Fanfic Idea (Title Pending)

Main Characters:

Gene: A care-free teenager with a past unknown, even to herself. She enjoys having fun and playing with other. She can be able to tell what people are feeling. One day she was pulled in a dark cyclone from her world. When she woke up she was in a forest. In the distance was a castle. She also found a cute baby in a odd round shape with wings and a crown (I'll let you guess which nicktoon character that is)

Johan: A young prince in his world. He may appear snobby, like most royalty, but is actually a very nice. At a young age, his mother left him and has never known why. He trained himself in swordsmanship and later inherited the Royal Guidance Keyblade like the rest of his ancestors. One day he learned that his father was missing after going to other worlds investigating the appearance of the dark cyclones in other worlds (and the appearance of a masked girl). Johan decided to go to other worlds to find his father, but not until the guards told him that they found a girl and a baby fairy in the forest.

Other Characters:
Meina: friend of Gene, like her, she is very extrovert
Pria: Other friend of Gene, aways quiet and likes to read books, not always fond of Gene's optimisim)
Julio: Gene's caretaker, He was the one who found Gene on a flower field as a small child.

Maxs: The captain of the guards and one of Johan's friends
Henry and June [Kablam!] :Guards in training, both very prone to accidents,
Neione: Daughter of the court wizard and one of Johan's best friends, always wanted to see other worlds (hopes to marry Johan one day)
Bein: The King's visor. He is a bit creepy but surprisingly helpful at times.
Matlon: Bein's apprentice. He doesn't talk much.

Please comment and tell me what you think.

Also, do you think Capcom character cameos will mess it up? Just wondering.
