To fit concubines into a Harry Potter fanfiction universe, one would need to re - imagine the social fabric of the wizarding world. For example, if the story was set in a time when wizarding society was more influenced by a culture that practiced concubinage. But this would also mean changing many other aspects like family structures, inheritance laws, and social hierarchies. It could also lead to a lot of conflict with the existing characters' values, as most of the main characters in Harry Potter uphold values like loyalty and equality in relationships.
It would be a very difficult fit. Since the wizarding world has its own norms like monogamous relationships in most cases (like the marriages we see in the series). If one were to introduce concubines, it would have to be in an alternate universe where the social and moral values are completely different. Maybe in a fanfic where the wizarding world is modeled after a more ancient and permissive society, but this would be a huge departure from the original feel of the Potterverse.
