To Where and Back Again, early thoughts and concerns?(spoilers)

Starlight Glimmer is apparently going to be the hero of the story with a new group of friends and the Mane 6 unable to help

Now I like the idea of Starlight needing to form a group of friends. In fact I'd love it if they had to do it with multiple ponies, like a group with Moondancer;

But I hope the Mane 6 aren't nerfed in this, I hope they're unavailable simply because they're elsewhere and can't be quickly contacted.

I've seen a few different ideas for her group. I'd like to suggest the main cast of Our Town; Double Diamond, Night Glider, Sugar Belle and Party Favor plus either Trixie or Sunburst
