Supernatural Oneshots and Imagines

A/N Help? (not an update)

Hi, readers, I need a bit of help - I want to make a series that's a crossover of my favourite show, Supernatural, and my favourite Disney movie, The Princess and the Frog, but I'm unsure about a few things that I could use help with:
Tiana and Naveen: Dean and Jo or Sam and Ruby?
Mama Odie: Pamela, Missouri or Bobby?
Ray and Evangeline: Cas and Meg or Hannah, Gabriel and Kali, or Balthazar and just Evangeline, or whoever you suggest?
Lawrence: Metatron or someone else?
Charlotte: ???
Facilier: Crowley or Lucifer?
And of course: frogs or something else?

I probably won't start writing it until I complete Can't Fight This Feeling though so that I don't confuse them :)

UPDATE: I've chosen Sam and Ruby as Naveen and Tiana, and Cas and Meg as Ray and Evangeline (I can't resist Megstiel!!!) and I was thinking either Benny or Dean as Louis - I am open to suggestions if anyone wants to comment any ideas :)

Seriously though, I need help with this
