Annabeth is a great choice. Her intelligence and strategic thinking could add a lot to the story. For example, when Percy and Grover are in a tight spot, she could come up with a clever plan to get them out. Another good character is Tyson. His strength and loyalty would be useful in battles and dangerous situations.
There's also 'The Lost Friendship'. This one focuses more on a time when there is a rift between Percy, Annabeth and Grover. It shows their individual growth as they try to mend their broken friendship. It's a more emotional take on their relationship and shows that even in tough times, their bond is unbreakable.
Jason is another good choice. He has a history with both Percy and Reyna. His leadership skills and his connection to the Roman side of the demigod world could bring in new plotlines. For example, he could help Percy and Reyna understand some of the more complex Roman demigod politics that they need to navigate.
Annabeth would be a great addition. Her intelligence and strategic thinking could add a lot to the story. For example, in a situation where Percy and Thalia are stuck in a maze - like the Labyrinth - Annabeth's knowledge of architecture and mythology could help them find their way out. She could also create some interesting relationship dynamics, like a friendly rivalry with Thalia.
The Hunters of Artemis could be a great addition. Since Thalia was once a part of them, it would be interesting to see how she interacts with them again, especially in the context of her relationship with Percy. Zoe Nightshade, if brought back in some way, could be a very cool character to include. She has a strong personality and a tragic backstory. Also, Clarisse La Rue could be in the story. Her tough - as - nails attitude and her rivalry with Percy could spice things up, especially when it comes to the relationship between Percy and Thalia.
Nico di Angelo would also be an interesting character to bring in. His dark past and his connection to the underworld could provide a contrast to the more positive and light - hearted relationship between Percy and Rachel. He might have his own motives that either help or hinder Percy and Rachel's mission.

Grover would be a great addition. In an AU, he could be Percy's best friend who is always getting him into (and out of) trouble. For example, in a college AU, Grover could be the one who convinces Percy to join a wild fraternity. He could also provide some comic relief. Another good character is Thalia. In a superhero AU, she could be a powerful superheroine with lightning powers. She could be a mentor or a rival to Percy and Annabeth, depending on the plot.
