I feel like her getting with Lucky and having a baby near the end was complete character assassination. I recall hearing the Fox pushed for certain things in the last couple of seasons and I suspect the push for her to get with Lucky, and Lucky becoming a reoccurring character was part of that.

In my mind, Luanne taking over Jack’s barber shop was the end of her character arc in the show. She’d finally found her calling and become a success. (Then suddenly we never see that Barber shop again and she backslides into just being a one dimensional dummy, but now pregnant and with Lucky to be annoying with in every scene.)
