Yes, it's possible. Sirius is a popular character in the Harry Potter series, and many fans like to imagine him in different scenarios in fanfiction. He has a complex personality and a lot of untold stories, so fanfiction about him in the context of 'Prisoner of Azkaban' can be very interesting.
Sirius might be a bit angry if the fanfiction misrepresented him. He was a proud Gryffindor and a loyal friend. If the stories made him out to be something he wasn't, like a coward or a traitor in a different way than what was in the real story, he'd be offended. But on the other hand, if the fanfiction showed his true essence and added more depth to his relationships, he might be quite impressed.
One could also write a fanfiction about Sirius Black's impact on Hogwarts during the events of Prisoner of Azkaban. For instance, his presence, even though he's on the run, could have a big influence on the students. Some students might start to question the Ministry of Magic's actions, and Sirius could inspire them to fight for justice.
In many fanfictions about Sirius Black in Prisoner of Azkaban, he is often given a chance for a new adventure. Writers might imagine him escaping Azkaban in more elaborate ways, or having different interactions with Harry Potter and his friends. For example, some fanfictions have him forming a secret alliance with other prisoners to break out together.
It can change the canon story by adding new perspectives. The Marauders' view might reveal hidden details. For example, they could know secrets about Hogwarts' layout that affect the events in 'Prisoner of Azkaban'.
One great fanfic could be 'The Lost Time in Azkaban'. It focuses on a new character who discovers a hidden mystery related to Sirius Black's time in Azkaban. Another is 'Hogwarts during the Prisoner's Threat' which delves into how the students' daily lives were affected by the news of the escaped prisoner. There's also 'A Different Perspective on the Prisoner' that tells the story from the point of view of a Hogwarts ghost.
One common plot idea is exploring Sirius Black's life more in - depth. Maybe a fanfiction could focus on his time in Azkaban before his escape, showing his mental state and how he coped. Another idea is changing the roles. For instance, what if Hermione was the one who was wrongly accused instead of Sirius? It would create a whole new dynamic.
