Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. Some fanfictions might focus on their unique relationship dynamics, perhaps exploring how fem Tsuna would interact with Reborn in different situations, like during training or in the face of danger.
One reason is that it gives more room for creativity. Writers can play around with how fem Tsuna would handle the situations that male Tsuna faced. And the relationship with Reborn can be developed in ways that are unique. For instance, there could be more of a focus on emotional support and less on just the typical mentor - mentee relationship. This fresh take on the characters makes these fanfictions popular among the fandom.
In many of these fanfics, a common theme is the transformation of Fem Tsuna. It could be her physical transformation as she grows more confident in her femininity, or her mental transformation as she becomes more powerful and assertive. Some fanfics also explore the idea of alternate universes, where the rules of the Katekyo Hitman Reborn! world are slightly different. This allows for different takes on the Reborn x Fem Tsuna relationship, such as them being from rival families or having different abilities.
In a great fem Tsuna and Reborn fanfiction, the world - building also matters. If it's set in the KHR universe, it should stay true to the basic rules and settings of that world. But if it's an AU, the new world created should be believable and detailed. The relationship between fem Tsuna and Reborn should be the central focus, with their interactions driving the story forward, whether it's a friendship, a mentorship, or something more romantic.
One common theme is adventure. They might go on quests together, facing various challenges and enemies. This allows for the development of their relationship as they rely on each other in tough situations.
