I'd like to see a spin-off where Homura and Sayaka team up with Kyouko, Mami, and Kugimiya.

Mami: "I'm not good at sports."
Kyubey: "You can't become a magical girl if you don't know anything about sports."
Mami: "Because I'm a girl, I can't participate in sports."
Kyubey: "If you want to become a magical girl, you have to know something about sports."
Mami: "I can't participate in sports because I'm a girl, but I'll be a part of a sports team."
