Bodyswap idea, these girls and our three fav small ponies

Chocolate: Molly Blyndeff and Scootaloo
Vanilla: Phoenica "Feenie" Fleecity the Fifteenth and Sweetie Belle
Strawberry: Bellatrix "Trixie" Roughouse and Applebloom

Note. Molly's button eyes and hair stars are a result of magic attached to her soul not her body

I actually would think Apple Bloom and Molly would have the most in common. Aside from being the leader, Molly is basically an earth pony through and through with her practicality. Trixie has the high flying nonsense and quick wits and motion of a pegasus down pat.
