If only this was canon. That’d be such a nice new beginning for everyone’s favorite sirens.

How the Dazzlings were reformed:
 
After discovering the mirror portal to Equestria, Adagio Dazzle stole Princess Twilight’s crown (the same way Sunset Shimmer did in the first EQUESTRIA GIRLS movie) before Princess Twilight herself sent Princess Sunset Shimmer to get it back. During the Fall Formal and having had enough of Sunset Shimmer, Adagio ordered her sisters to kidnap Ray before Sunset gave chase to the front of the school where Adagio threatened to smash the portal with a sledgehammer if Sunset refuses to surrender the Princess of Friendship’s crown. With the crown acquired, Adagio put it on and transformed into the same she-demon Sunset was when Twilight battled her. Using the magic of Friendship being emitted from the crown, Sunset Shimmer defeated the Dazzlings and all three of them accepted the honor of becoming her new pupils (just like how Starlight Glimmer gave up her sinister ways and became Twilight’s pupil). Sunset mentioned how she was willing to teach Adagio, Sonata and Aria of what she and Twilight already know about friendship as the four girls headed back home to Equestria. All of Canterlot High was safe and sound from the Dazzlings’ devastating song (because the Dazzlings became ponies and not sirens anymore). But then, a new trio of villains known as the Panda Lilies, Cassandra Storms, Persephone Morning and Daphne Sky (who are secretly banshees as well as the heralds of the ghost of offline Decepticon commander: Starscream) came along and are collecting the souls of humans and ponies with their singing charms to bring their master back from the grave! Learning about the new hostiles intruding Canterlot High, Sunset Shimmer informs her students that the banshees are very dangerous spirits from the underworld and want to revive Starscream from his demise by gathering enough human and pony souls that Starscream may arise a walking bacteria virus, a plague upon humans, ponies and transformers, an unholy abomination with the strength of Optimus Prime, power over even Twilight Sparkle’s Alicorn magic and the glory of indestructibility (if he is released from his sarcophagus on the planet Cybertron). Can Sunset Shimmer, Starlight Glimmer, Spike, the Mane Six, the Autobots and the Dazzlings be able to thwart the banshees and prevent Starscream’s resurrection?
