Shitcanning Kathleen in the most brutal and humiliating fashion possible would be a good start. Don't just quietly dismiss her and have her "step down" or "move on to other projects", make a big spectacle out of it, like burning a witch at the stake.

Have a big event at Star Wars Land and tell her she's there to accept some sort of award. When she walks out, instead of presenting her with a trophy, Iger dresses her down, degrades her, and tears the sleeves off of her pantsuit. He gives a quick speech about how she's disgraced the good name of Star Wars and that she has exactly 5 minutes to escape Disney World before a randomly selected group of Star Wars fans dressed as stormtroopers are released to hunt her with paintball guns.

Until Kathleen is gone and a MAN is put in charge, I'm not buying a single fucking Disney product because otherwise it won't be sincere.
