One possible plot could be Hermione using her knowledge to help the Marauders in some way. For example, she might assist them in dealing with a difficult spell or situation that they were struggling with in their original time. Another plot could be her trying to change certain events that she knows will have negative consequences in the future, but then facing the moral dilemma of interfering with time.
Perhaps Hermione travels back in time to stop a dark wizard from influencing the Marauders in a negative way. This would involve her using her wits and magical abilities to outsmart the dark wizard. She might also have to work undercover to avoid changing too much of the past. Along the way, she could form strong friendships with the Marauders, and they could learn a great deal from her, like new ways to study magic or different perspectives on the wizarding world.
