Marks for effort alternate plot

I’ve been thinking of an alternate universe, during the mlp episode “Marks For the Effort”, the Dazzlings appear as ponies with repaired but improved amulets, to help the CMC as they are repeatedly refused into the School of Friendship by the Mane 6, promise to teach them, rather than rely on the incompetence of Miss Cheerilee.

The CMC, at first unsure of these 3, soon follow their lead, learning new songs and given amulets and soon...they become the mini siren ponies!! Muahahahaa! They march to the School of Friendship and with these new amulets, sing away and every creature/pony argue and fight much to Twilights distress.

“This would never have happened if you’d just let these poor neglected fillies into your school...Princess Twilight.” Adagio cackled and the other two sirens snicker.
