Which Harry Potter house would the FiM cast be in?

[MyLittlePonyTales]

So, which HP house do you think each of the characters would be in?

Doesn't have to be the main six, secondary (characters with one episode or more) are welcome.

For me:

Twilight Sparkle - Ravenclaw

Rainbow Dash - Gryffindor

Rarity - Umm.... Ravenclaw?

Pinkie Pie - Hufflepuff or Slytherin

Applejack - Gryffindor

Fluttershy - Hufflepuff

Derpy - Hufflepuff

Angel Bunny - Slytherin

Apple Bloom - Gryffindor

Sweetie Belle - Ravenclaw

Scootaloo - Gryffindor

Princess Luna - Ravenclaw

Princess Celestia - Gryffindor

The Great and Powerful Trixie - Slytherin

Gilda Griffon - Slytherin

Spike - Hufflepuff

Vinyl Scratch - Ravenclaw

Big Macintosh - Gryffindor
