Well I didn't want to get into it, but he's a Satanist.
Every full moon he sacrifices 4 puppies to the Dark Lord and smears their blood on his paino.
This should help you understand the score for Wicked a little bit more.

I don't know Carol Channing, but I suspect she would find this charming. Johnny Depp does some broad charicatures (Ed Wood, Fear and Loathing, Pirates) but it always seems to come from an honest place. I doubt he would portray her in a cartoonish manner.
It could be great. Like when Cate Blanchett was the most convincing Bob Dylan of like 6 in that movie that was sort of about Dylan, but not really, a few years ago.

Carol Channing is a bit of a caricature, which I think she's pretty much aware of, and I bet would get a kick out of Depp playing her! She's a good sport and a legend!
I had always heard that Ms. Channing was very fond of her send-ups in Forbidden Broadway. I would imagine she would take Depp's wish to play her as a compliment.
