You mean like how FDR threatened to do that during the new deal, and then the court backed down and let all sorts of unconstitutional stuff through?
When we ended a government of enumerated powers and everything could be done at the federal level without an amendment - great things like the drug war.

FDR packed the court with his own judges when others had retired during his term. That's how he got the New Deal through, not on threats or cowing.
