One possible fanfiction idea could be that Bella, as David's sister, has a conflicted relationship with the vampire gang. She might try to keep David from getting into too much trouble while also being drawn to their wild lifestyle. For example, she could be the voice of reason when they plan their hunts, but at the same time, she has her own vampire instincts that she struggles with.
The story could also take a different turn in terms of the plot. If Bella is David's sister, she might have some influence over the group's decisions. For instance, she could convince them to target different prey or to avoid certain areas. This would change the way they interact with the human population in Santa Carla. And if there are other vampires who are enemies of David's gang, they might use Bella as a way to get to David, adding a whole new layer of conflict.
One key element is often the exploration of a new relationship dynamic. Since they are not a canon pairing, it's interesting to see how they interact. Another element can be the alteration of the existing story's setting to fit their relationship.
A fanfiction that stands out is 'Parallel Paths'. This story takes Bella Swan and David Mates on parallel but intertwined paths. It starts with them having their own separate lives but then circumstances bring them together in a very unexpected way. The author does a great job of building their relationship gradually. There are also elements of mystery and adventure in it which add to the overall appeal.
One more way is if Bella is an artist. She starts painting portraits of the Lost Boys without knowing their true nature at first. When David sees her paintings, he is drawn to her creativity and the way she seems to capture their essence. This leads to a series of interactions where they slowly open up to each other, with Bella gradually accepting David's vampire world while David discovers the beauty in Bella's art and her human side.
Another idea is that Bella and David were once childhood friends before he became a vampire. When they meet again in the context of the Lost Boys, old feelings resurface. However, the fact that David is now a vampire creates a lot of conflict, especially when Bella discovers the darker side of his new existence.
