One idea could be a story where Bella discovers the world of the Mikaelsons after being turned into a vampire. She crosses paths with Elijah and they form an unlikely alliance to deal with a common threat in the supernatural world.

A really interesting storyline could be Bella trying to reconcile her old life in Forks with her new life as a Mikaelson. She might struggle with the differences in values and lifestyles. For example, the Mikaelsons are more into power plays and manipulation in the supernatural world, while Bella was used to the more straightforward (although still complex) relationships in 'Twilight'.

Well, there are fanfictions that play with the idea of Bella's mind - reading ability (if it was more developed) and how it would interact with Klaus's complex and often secretive mind. It could lead to some intense mental battles and also a deep understanding between them. Some stories might also explore a romantic relationship where Klaus, who is used to power and control, has to learn to be vulnerable around Bella. And vice versa, Bella has to adapt to Klaus's more brutal and ancient ways of dealing with things. They could face challenges from both their own 'families' in the respective fictional worlds, like the Cullens being wary of Klaus's intentions towards Bella and Klaus's siblings having their own opinions about his newfound interest.
