i'd lay off the lame puns. if you want episodes i'd do, please visit my thread in Itchy and Scratchy Studious.
basically, i wouldn't have a lot of guest stars, i'd have more family-related episodes (i.e. not ones all about, or mostly about, homer), and whatnot. i'd make the show more centered on the family and focus less time on guest stars, secondary/recurring characters, and i wouldn't have most of the episodes be homer-centric (sure, he's a central part to the family, but he has more episodes then probably bart, marge, lisa and maggie do combined, i'd guess)
