Mane Six: Replace One with a minor/background character

If you could swap one of the mane six for a minor or background pony, what would you swap? The pony you replaced still shows up every once in a while as a minor recurring character.

I'd ditch Applejack and throw Cherilee into the group...somehow.

Switch out Applejack with Pinkie Pie in your answer and I'd agree with you.

Cheerilee is epic.

I don't know who to switch out. But I think headcanon Lyra would be awesome as a replacement :P

I would switch Pinkie with Big Mac.

Topic creator, I love your avatar.

Take out Applejack, replace her with Cheerilee

Take out Rarity, replace her with Ghost.
