Edie would have her own storyline if she was in season 7, surely finding out Paul killed Martha and being dragged into the Paul/Felicia storyline instead of Susan. Edie was Martha's best friend, and Karen suddenly being revealed as her friend seemed forced because they knew Edie wasn't around anymore.

As for Katherine maybe she can be killed off in season 5 by Dave and he does kill her on the trip in the woods.
