Rider swap for tall kids

Can I rider swap my 7 year old, who is 52" tall, because she is scared to ride Everest and Dinosaur? Or only little guys?

I’ve read mixed experiences with older kids but this is what their official RS page says. I believe the language includes kids who may be tall enough, but unwilling, to ride. Maybe screenshot this page and show it to a CM if they give you flak?
