Is there any equivalent of "roll over in his grave" for someone who is alive?

Recently my friend and I were talking about something that would cause great dismay to our other mutual friend, and he said “if X knew about this, he would roll over in his grave, if he were dead.” Which is funny but also made me think how there’s not really any equivalent expression for someone who is alive. Sure, I can say that it would cause him great dismay, but that feels a bit formal/stilted and also a bit of an understatement. Am I forgetting anything?
