A plotline could be that the Marauders' old secret hideout is discovered by Harry, Hermione, Neville and Luna. Inside, they find a series of enchanted journals that detail the Marauders' adventures and also some unfulfilled plans. They decide to carry out these plans in the present day to help fight against a new dark force that has emerged in the wizarding world.
There could be a story where Luna has a strange vision about the Marauders and she drags Harry, Hermione and Neville along to investigate. As they dig deeper, they find out that there are lingering spells from the Marauders' time that are now causing chaos in Hogwarts. They have to work together to reverse the spells and in the process, they learn a great deal about the Marauders and themselves.
Imagine a fanfiction where Harry, Hermione, Neville and Luna are all put into a magically - created alternate reality where the Marauders are still alive. They must find a way to get back to their own reality while also helping the Marauders deal with a threat that exists in this alternate world. This would allow for a lot of interesting character interactions between the different generations of wizards.
