From a purely financial standpoint, this is a great idea. First, it's Beetlejuice round 3, so not exactly anything serious/high-brow/etc. Second, she's really done a great job rebuilding her public image (as much as she can at this point), and a lot of her Beetlejuice cosplay TikToks went really viral a few years ago. Considering she sold out the St. James for her concert show (and she isn't a great singer, for what it's worth), she will probably sell some tickets. Also, they're expanding a small part she can play, too, which is better than stunt casting her in any of the principal parts. Not sure if it's a hot take, but this isn't the worst idea.
