Moshi monsters fanfic?

I'm thinking about making a Moshi Monsters fanfic. It's gonna be called Moshi Charmed, so basically it's about four monsters who attend the moshiversity. The main girls are Eeva (a poppet), Trinka (a katsuma), Krystal (a zommer), and Lauri (a luvli). the girls are given magical charm bracelets by their homeroom teacher Ms Scarri, the bracelets can give them magic powers however they made a promise to never ever lose the bracelets because in the wrong hands who knows what would happened. I'm still thinking of the villains though but i'm still debating if I should make it or not. Should I make it?
