In some fanfictions, the friends' letters in OotP could be a way to introduce new magical elements. For instance, a letter might be sent on a special parchment that has the ability to transform into a small creature to deliver the message more quickly. Or perhaps the letters are charmed in such a way that when they are read, they create a temporary magical scene related to the sender's current situation, adding a new dimension to their communication.
The letters can show the closeness of their relationships. If the letters are filled with inside jokes and affectionate nicknames, it indicates a strong bond. For example, Ron and Harry might use terms like 'mate' often in their letters.
You could write a fanfiction where the members of Dumbledore's Army start to have doubts about Harry's leadership. Some might think he's too reckless. This could lead to a split in the group, and then they have to figure out how to come back together when they realize they are stronger united. It would add an interesting layer of drama and character development to the story.
In some fanfiction, you might find letters from Harry to Sirius that are full of his thoughts about Hogwarts life. These letters often express his concerns about Voldemort's return in a more personal way than in the original books.
One great 'Harry Potter' fanfic about letters could be where the Hogwarts letters are intercepted by dark forces and the story follows how the wizarding world copes with it. For example, it might lead to a secret mission by the Order of the Phoenix to re - send the letters to the Muggle - borns.
Another possible storyline is that they become friends after an accident. Maybe during a Quidditch match, there's a terrible accident and they have to rely on each other to survive. This shared experience makes them see each other in a new light and they start to build a friendship. They then help each other deal with their respective family issues. Draco can give Harry insights into the pure - blood families' ways, and Harry can show Draco a different way of looking at the world, not just through the pure - blood ideology.

A more comical storyline could be Crookshanks accidentally getting into a magical mishap that gives him the ability to talk for a day. He then spends the day criticizing Ron's treatment of him, while also sharing some of the secrets he's learned from prowling around the Gryffindor common room at night. Hermione is both amused and exasperated as she tries to keep Crookshanks out of trouble.

They could combine their unique skills, Harry's magic and Byakuya's combat abilities.
