All the points I brought up in my own thread NAPOLEON WINS WATERLOO, WHAT NEXT?
France is bankrupt and bled white. The only way for Napoleon to stay in power is politically, not militarily. And NO one is willing to make any sort of deal with the Ogre of Europe. So it's just not going to happen, he is either killed or exiled a second time...
It seems that you did not notice: the proposed "victorious" scenarios are based upon changed political situation (probability of such a change is a completely different issue).
