Well, one possible plot could be that Hermione is on a quest in Hogwarts to find a hidden spell book. She discovers that the key to unlock the room where the book is kept is locked in place by a magical charm. She has to use her intelligence and knowledge of various spells to break the charm and get the key. For example, she might first research about the origin of the charm in the library, then try different counter - spells she has learned over the years.
Another plot could be that the key is locked in place by a mischievous house - elf. Hermione has to bargain with the house - elf to get it released. She tries to use her knowledge of house - elf rights and magic to persuade the elf. In the process, she might learn more about the hidden secrets of Hogwarts that are related to the house - elves and their magic.
Maybe the key is locked in place as part of a protection mechanism for a powerful magical artifact. Hermione could be part of a group (including Harry and Ron) who are trying to retrieve the artifact before the bad guys get to it. She has to figure out how to unlock the key by solving a series of magical puzzles. Each puzzle is related to a different subject she has studied, like Transfiguration or Potions.
One possible plot could be that Hermione's kid inherits her love for knowledge. Maybe the story shows the kid starting at Hogwarts and struggling to live up to the expectations of being Hermione Granger's child.

One possible plot could be that Oliver, being the Quidditch enthusiast, asks Hermione for help with strategizing for an important match. Hermione uses her intelligence and knowledge of spells to come up with unique plays. Along the way, they develop a mutual respect and friendship.
Hermione might also think about the reason why she's locked in. Is it a trap set by an enemy? If so, she'd start to plan how to outwit them once she gets out. She could use the time she's locked in to prepare herself mentally and magically. She might even try to find a way to turn the situation to her advantage, like using the room's contents to create a new spell or potion that could help her later.
One possible plot could be that Hermione, with her intelligence and quick - learning ability from the Harry Potter world, gets drawn into the complex underworld of the KHR universe.

For example, she could use her spell - casting knowledge in a way that mimics the special powers in the KHR world, allowing her to outwit her opponents.
Well, perhaps it's part of a rescue mission gone wrong. She's pushed up against the porthole while trying to escape from some dark wizards. Her friends are nearby but are preoccupied with fending off other threats. She might be using the porthole as a vantage point to look for an escape route or a way to signal for help.
Maybe Hermione is on a long and arduous adventure in the Forbidden Forest. She's been walking for hours and there's no proper place to relieve herself. She has to pee but she's also worried about being attacked by some dangerous creatures. So she has to keep looking for a safe spot while constantly being distracted by the growing need to pee.
One possible plot could be that there is a competition in the wizarding world to create the best cross - fictional costume. Hermione decides to go all out with a Princess Leia look. As she prepares for the competition, she starts to study more about Princess Leia's character and finds inspiration in her leadership and determination. This makes Hermione more confident in herself and she not only wins the competition but also uses what she's learned to stand up to some bullies in the wizarding world. The fanfic could focus on her personal growth through this experience of dressing as Leia.
Well, one possibility is that Hermione uses her intelligence, like she did at Hogwarts, but in the world of hitman. Maybe she'd use spells in a creative way to take out targets without being detected. For example, she could use the invisibility spell to get close to her mark.
