So, for such an impact, you would almost certainly need the strongest bouncing lander ever produced. However, Pluto's escape velocity only is about 1/10th the speed of NH. This means that if that first bounce upon impact would result in even 10% of the initial velocity, it will literally bounce out of the system and back towards the sun.
