How can I get this idea over to Eddy and Adam?

I have a suggestion I really wanna see happen! I really want Michael Keaton on the mostra and I have a character idea for him. I was thinking he could play this very powerful,very dangerous and very evil sorcerer who has the ability to shapeshift into a very powerful bird who can breathe fire. His other powers include turning other birds into demon like birds and have them be his minions. He can also conjure fireballs from his hands and stuff. He might very well be even più powerful then Rumple. Another part of my idea is that he and Rumple start off as enemies but then decided with their powers combined, they can succeed and conquer. His costume could be dark blue with black feathers and a cool cape and a bird shaped head piece. Here's something else, he's also Maleficent's father! He's the one who taught her how to shapeshift into a terrifying beast! He finds his way to storybrooke to find Rumple and continue their plan! His backstory is that when he was little, his parents were killed da a group of townspeople accusing them of sorcery cause his parents also possessed magic. He then grew up an orphan discovering on his own different spells to exact revenge! He meets a woman (haven't decided who she could be except that she's to be Maleficent's mother!) and they fall in Amore after discovering they're both learning magic skills. I kinda got the bird idea since Keaton is obviously known as Batman and his most recente award winning film is Birdman! Plus I've always wanted to see him play a sorcerer. Loved his villain performances in a few of his Film where he plays villains so I really think it'd be cool if he'd come on the mostra as an evil and extremely powerful sorcerer. I thought he could be a final season villain where he and Rumple unisciti forces with several well known villains including Maleficent. Hopefully Regina is still fighting for the side of good during this time so maybe they could try to get her to unisciti forces with them with her almost agreeing but deciding
