Can you see it? I can definitely see it

Double Diamond - Ice types
Sugar Belle - Food-based Pokemon
Party Favor - Uh... I don't know
Night Glider - Dark/Flying types

4264662 Then who'd the Champion be?

The Elite Four is just what the group is called. Nothing more.

4264664
If there's a champion, it'd be Starlight Glimmer.

Her entire team would consist of Dittos.

4264668 Dittos? I'm pretty sure that they'd fit more into Chrysalis and not Starlight.

If anything, I'd say that Starlight's Pokemon would be the same level, and have exactly the same stats, name, or moves...

4264665
I'm not really feeling "Elite Four" as a good choice for their group name, but that's just me...

4264938 They don't have an official group name, so I went with that

4264662 Party Favour/Utility/Prank?

4264660
Sugar Belle - Fairy
Party Favor - Psychic
Night Glider - Dark or Ghost
Double Diamond - Ice or Dragon

4265055 It's the fetlock four, duh.
