Probably not. As assassins, they were necessarily opportunistic. But as coup plotters, they needed more than mere opportunity, they needed a political rationale, which a ‘successful’ Hitler would have denied them.
Actually, plotters within the Wehrmacht had been planning to remove Hitler since 1938.
Their hope had been that the Western powers would have held out at Munich, whereupon they planned to put him uner arrest and try him for the abuses of his power and his crimes. Unfortunately, this plan went sour... :-(
I’ll never understand why some German soldier or officer didn’t simply pull out a pistol and shoot the schweinhund in the head.
