Another possibility is that there is some sort of magic that binds them together. This magic could be initially a mystery, and as they try to figure it out, their feelings for each other grow. It could be a magic that only affects them and has something to do with an ancient Equestrian legend.
Perhaps the story is about Twilight falling in love with someone who is different from the ponies she usually interacts with. This could cause some conflict within the Ponyville community at first, but as they see how much they care for each other, they come to accept the relationship.
A plotline could be that the protagonist is a new pony in Ponyville who catches Twilight's eye. They start to interact more and more, and a romance blossoms. For instance, they meet at the library when the new pony is looking for a rare book.
Another plotline could be a time - travel story. Twilight accidentally travels back in time to when Sombra was first becoming evil. She tries to change his path and prevent him from turning into the dark villain he became. This would involve her getting to know the younger Sombra and trying to influence his decisions with her knowledge of the future.
One possible aspect could be that the story might explore the unique bond between Twilight and the narrator. Maybe they start as friends in the Ponyville setting of MLP, gradually realizing their feelings for each other.

One possible plotline could be Luna seeing Twilight's potential and taking her under her wing to teach her some ancient and forgotten magic. This would lead to Twilight having unique abilities and a special bond with Luna.
One possible plotline could be that Twilight discovers her best friend has been secretly working against her all along and planned something devious for the wedding.

Another could be that Twilight is betrayed by a new acquaintance who she thought was a friend, but in reality was an enemy in disguise, leading to chaos at the wedding.
A common and interesting plotline is Sombra's redemption. Twilight often plays a key role in this, like in 'Sombra's Redemption' where she helps him see the error of his ways. Another is their teamwork. In 'Twilight and Sombra: Against the Dark Forces', they team up to fight a greater evil that neither could face alone. It shows how their different powers can complement each other.
Well, it could be about a whole bunch of things. It might be a story that focuses on the relationship between Twilight and the author or a self - inserted character.

It could also explore their friendship, or perhaps a magical quest where Twilight's knowledge and skills are combined with the experiences of the other character.
One possible plotline could be that Lucy has a hidden talent for singing, and in the Twilight world, she uses her singing to attract the attention of a certain vampire or werewolf. Maybe it creates a new kind of bond or rivalry among the supernatural beings.
One possible plotline could be that a character is using a hammer and a nail to build a shelter in the forest near Forks.

Another could be that the hammer and nail are used to repair a special object that has some significance in the Twilight lore, like a charm or a family heirloom.
One possible plotline could be that some kind of magic or power from the MLP world affects the Naruto characters in terms of their ability to breed or reproduce in a new and strange way. Maybe there are ponies that have a special power that they accidentally transfer to Naruto characters, leading to a series of events where they have to figure out what's going on.
A plotline could involve Sombra's spirit lingering after his defeat. Luna, being attuned to the more mysterious aspects of Equestria, detects this. She tries to communicate with his spirit to learn more about his motives. This could lead to a journey of self - discovery for both of them as they explore Sombra's past and Luna's role in understanding the darkness within Equestria.
