Here's an idea and link to a picture for a sequel to the "The Wandering Juvie" which is if the show made a spinoff set 12 years ahead:
Season 33, Episode 11: "Queen of the Hill" Maggie's accidental, yet careless biking into a busy intersection while wearing headphones causes her to fail to notice a cargo truck coming towards her. Swerving at the last second, the truck crashes through a storefront, causing nearly 30,000 dollars in damage. With a somewhat spotty juvenile record, Maggie is sent to Juvenile hall and the Head Officer is a reformed Gina (from "The Wandering Juvie"). Unlike her older brother, Maggie's got an edge--she's already a very tough girl when she needs to be, and her first goal is to kick the toughest girl's rear. Meanwhile, Gina sees Maggie's mean streak and it reminds her of herself during her stay and she wants Maggie to 'go straight', and she also wants to meet up with Bart and see how he's doing nowadays, too.
