A really interesting plot could be set in an alternate universe where Galen Marek never turned to the dark side. He and Ahsoka meet during a mission to save a planet from a natural disaster. They find out that there are dark forces trying to take advantage of the chaos. Together, they have to fight off these forces while also trying to save the planet and its inhabitants. Galen's knowledge of the Force in a more positive light and Ahsoka's wisdom as a former Jedi Padawan combine to make a great team.
One idea could be that Galen Marek and Ahsoka Tano team up to face a new Sith threat. They might initially be suspicious of each other due to their different backgrounds. Galen with his training under Vader and Ahsoka's Jedi training. But as they work together, they start to respect each other's skills and form a strong bond.
It could develop into a friendship based on mutual understanding. Galen has had a difficult past, being manipulated by the Sith. Ahsoka also has her own traumas from leaving the Jedi Order. They could bond over their shared experiences of feeling like outsiders in a way. They might share stories of their pasts and find common ground, which leads to a deeper connection.
They might start off warily. Galen, being used to the ways of the Sith, would be cautious around Ahsoka, a Jedi. Ahsoka, on the other hand, would be on guard but also curious about Galen. Eventually, they could start to exchange combat techniques and stories of their past experiences.
One interesting fanfic could be about Galen Marek's early training. It might explore his relationship with his master in more depth than the official story. For example, how he overcame difficulties during training.

Well, Galen Marek in Star Wars Rebels fanfiction is a great concept. His relationship with the dark side and his journey back to the light (if that's how a fanfic writer takes it) can be a source of inspiration. He could be a mentor figure to the young Jedi in training like Ezra. His combat skills and knowledge of the Sith could be used to outwit the Inquisitors. Fanfic writers can explore how he adapts to the Rebels' way of life, which is so different from what he has known in the past.
