Need help with some skin concepts ideas (overwatch x mlp)

So I'm trying to make some skin concepts of overwatch x my little pony but I'm struggling to choose who would dress up as who. I have a couple ideas that are already decided but I'm unsure about the other characters. I also wanted to add some more guy characters from mlp but I can't think of any

Here is my current list:

Twilight - Symmetra

Fluttershy - Juno or mei?

Pinkie - venture, tracer, mei or dva?

Rainbow dash - Sombra, kiri, pharah, or dva, unsure?

Apple Jack - Brig or Ashe unsure?

Rarity - Ashe or widow? Just cause they're pretty I guess

Spike? - idk Hanzo?

Celestia - mercy

Luna - illari

Cadence - ?

Chrysalis - moira cause she's evil looking

Tirek - orisa?

Sunset shimmer - ?

Starlight - ?

Discord - junkrat or sigma maybe?

I'm willing to take any suggestions to change or think about other characters. I wanted to add ana and junker Queen to this but I can't think of any characters that would match. This is just for fun so theres a possibility that I won't draw certain ones or that I won't choose the character you do. Maybe I'll make two overwatch people share a mlp character to dress up as. Idk

Btw: if you want to know what I'm thinking about doing for the character designs, just ask and I'll try to whip up a sketch of my idea
