One common theme is love. Since Boa Hancock has a crush on Luffy, many fanfics explore how this love could develop. Another theme is adventure. Luffy is always on an adventure, and fanfics often involve Boa joining him in his escapades.
The theme of self - discovery can also be present. Hancock might discover new sides of herself because of her relationship with Luffy. For example, she could become more open - minded or learn to trust others more, which is a big step for her as the empress of Amazon Lily.
A big theme is also about breaking barriers. Hancock is a proud and strong woman from Amazon Lily, and Luffy is a carefree pirate. Their relationship in fanfics often shows how they break cultural and social barriers between them. For example, Hancock's tribe has certain traditions and views about men, but with Luffy, she defies some of those. Also, friendship is a theme as Luffy values friendship highly and Hancock becomes part of his circle of friends in a special way.
First, you should have a clear idea of the relationship you want to portray between Luffy and Hancock. Decide if it's going to be a romantic relationship, a platonic friendship, or something else. Then, think about the setting. You could set it in a new island they discover together or during a major event from the original story but with a different twist. For example, during the Marineford War, but what if Hancock had a more active role in protecting Luffy from all sides?
One popular theme is Hancock's unrequited love for Luffy and how she tries to deal with it. Another is their adventures together, perhaps teaming up against a common enemy. Also, the cultural clash between Luffy's carefree nature and Hancock's more reserved and proud Amazon Lily ways.

Often, the theme of adventure might be intertwined. Given that Luffy is all about exploring and Boa has her own story in the One Piece world. Their relationship could be set against the backdrop of new adventures they embark on together. Another theme could be the discovery of emotions. Luffy is not always in touch with his romantic feelings, and Boa has her own complex emotions, so fanfics may focus on how they come to terms with their feelings for each other.
