For example, the middle-school-aged Bobby Hill was great for tons of laughs back in the show’s original run, but the thought of Bobby as a legal adult and what the show could do with that is incredibly fun to consider.
That said, age is just a number, and while The Simpsons can still write perpetual storylines for their ageless characters, perhaps Mike Judge can find more inspiration with an older King of the Hill character lineup.
If it’s incredible to think of from a fan perspective, then one can only imagine what ideas Judge already has in mind provided Fox would be cool with his bold new direction for the series.
