Maybe a plot where the wolfpack discovers that polyamorous relationships are actually a part of an ancient wolf tradition that has been long forgotten. So, they start exploring this new (to them) relationship style. They face challenges from other werewolves who don't understand or accept it, and they have to fight to keep their relationships intact while also upholding their place in the werewolf community.
A story could revolve around a member of the wolfpack having a vision or premonition about a polyamorous relationship being the key to saving the pack from a great danger. As they start to form these relationships, they learn more about themselves, each other, and their combined powers. They then use their newfound unity and strength to face the impending threat.
Leah Clearwater could also be a central character. She has her own complex story within the wolfpack. Maybe a visiting werewolf from another pack, who is more open - minded about poly relationships, could come into the story and start a relationship with Leah and some of the male pack members. Another option could be Seth Clearwater, as he is a likable character and could be part of a poly relationship dynamic within the pack.
One common theme is loyalty. The wolfpack members are extremely loyal to each other, and this is often emphasized in the fanfiction. For example, in many stories, they will go to great lengths to protect one another.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often a ton of Twilight Wolfpack fanfictions there.

One interesting plot idea could be exploring how different characters adapt to the post - apocalyptic world in new and unexpected ways. For example, a character who was once a timid office worker becomes a fearless scavenger.
One plot idea could be a hockey player who discovers he has a special power during a twilight game, like being able to skate at super - speed. Another could be a love story between a hockey fan and a player, set against the backdrop of twilight - filled evenings at the rink. Maybe a story about a hockey team's struggle during the twilight of their careers, with an old - timer coming out of retirement to save the day.
One idea could be exploring the origin of the psychic powers in the twilight world. Maybe there was an ancient event that triggered it.
A fanfiction could explore the idea of a character from Twilight becoming a Shadowhunter. For example, Bella could discover she has Shadowhunter blood and has to leave the vampire - werewolf drama behind to learn a whole new set of skills and rules in the Shadowhunter world. It would be interesting to see how she adapts and how her relationships with Edward and Jacob change as a result.
One idea could be exploring a different origin for the vampires in the 'Twilight' universe. Maybe they are not just a natural occurrence but were created by an ancient magic gone wrong. Another could be a story where a human character has the power to control the elements and how that changes their relationship with the vampires and werewolves.
One plot idea could be exploring the backstory of the characters in the 'awoken twilight' world. Maybe there was a great war or a magical event that led to their current state. Another could be a love story between an awoken and a regular human, dealing with the challenges of their different existences.
One idea could be a story where a new wolf joins the pack with a special power that helps the pack in a new and unexpected way, like being able to communicate with other animals and warn of impending danger. Another could be a love story between a wolf from the pack and a human who is somehow connected to the Twilight world. For example, she could be a relative of Bella's and through her, the wolf discovers new aspects of the vampire - human - wolf dynamic.
