Yes, there are. You can find them on various fanfic platforms like FanFiction.net. Some of these fanfics explore their relationship in unique ways, perhaps delving into their family bonds or creating alternate storylines where they interact more closely.
In my opinion, the story of TotK is quite good. The plot is engaging, the characters are well-developed, and the world-building is immersive. There's a nice balance of action and emotion.
The length of the main story in TotK can vary depending on how quickly you progress and how much exploration you do. Generally, it can take a decent amount of time to complete.
A fanfiction could also be about their childhood memories. Maybe there was an event in their past that they both remember differently, and as they talk about it, it reveals more about their characters and how they've grown over the years. It could be a heartwarming story full of family bonds and the magic of reminiscing.
One interesting fanfiction could be about Twilight and Shining Armor's childhood adventures that were never shown in the original series. Maybe they had a secret magical place they used to go to and explore together.
Sure, there are many out there. Fanfics often take creative liberties. In some, they might be involved in solving a big mystery together in Canterlot. The relationship between them can be portrayed in various ways, from a strictly brother - sister type of protectiveness to a more unique and untraditional bond that still respects the essence of the My Little Pony universe.
Another theme is loyalty. Shining Armor's loyalty to Twilight and vice versa. They are always there for each other no matter what. This can be seen in fanfictions where one of them gets into trouble and the other drops everything to help.
