Around 2013, an artist called Simpspin started a fan series titled "Maggie and Eric". It takes place in an alternate Simpsons future where Homer and Marge had a fourth child named Eric, Maggie grows up to be a brute who resents Lisa, Bart works at a radio station with Jessica Lovejoy and Lisa is a traveling Jazz Musician. He wrote many episode summaries for his hypothetical series. There were even some fan scripts on nohomers.net that someone wrote on it. The only one I actually read was "Queen of the Hill" where Maggie goes to Juvie and Bart reconnects with Gina Vendetti. Unfortunately I tried to find the script again but it seems to have been deleted. So this is me using what bits of my memory I have left to provide a, very bad, outline of how the episode went.
The One-shots revolve around the journey of a devoted single father navigating the complexities of parenthood and his deepening bond with his sons.
Each story highlights the unique challenges and heartwarming moments they share, capturing the essence of love, resilience, and the unbreakable ties of family.
