You should do a story where MCR is still in their bullets stage (traveling around) and featuring Gee and Mikey's grandma, who I believe was religious. Then you can create a band that starts touring with them, but have like three girls in it(who are from the same town as Mikey and Gee, but a couple years older/younger), so they can be the love interests, of course. And for the make believe part, you can make the other band demon/vampire slayers/angels "on a mission from god". And these girls know Elena because earlier in her life she trained them. And the guys should find them killing shit in an alley or something, and if you want (as the story goes on) When Elena dies, have one them become preggers because Elena was an "old soul" and is being reincarnated. Just an idea... and kind of incomplete and not thought out...
