Everything I've read (granted, not as extensive as many here) indicate that Nap never planned for a total victory, and that he was quite wishy washy on any sort of nation building in Poland. He expected Russian troops would come out to meet him at the border, he would beat the crap out of them, give them a pleasant peace, while taking a little bit just to be punitive (it was his MO for all the major powers), and probably totally screw over the Polish. He was kind to any who he thought was a major power, and ran roughshod over the rest.
Russia messed him up because they didn't behave according to plan, and he was left with attempting to do what he should have known he couldn't do. IF, by some miracle, his perseverance had paid off, he'd have stuck to his original plan, with maybe a little more punishment for his troubles, thanking his lucky stars he could get out while the getting was good. Or, maybe he'd be obstinate and obtuse and pushed on for more (ala Spain) and ultimately lose. It'd take two miracles to have him achieve complete devastating victory, and a third miracle to have a complete revamping of the russian scene turn out well for him.
