Not a chance, Stalin was a coward in that for example its arguable whether he would attack Poland without german invasion
I think if the Poles had a well-equipped guerilla army with the sole intention that the army would blend in with civilians, Stalin wouldn't have wanted anything to do with it. I've always, always wondered why Poland tried to fight a conventional war - if she had learnt the lessons from the Irish War of Independence, she might very well have survived intact.
Stalin certainly wouldn't have wanted to put Russians into a strange environment in which they were being picked off by men, women and even children without them having a clue as to who might actually have a gun. As for the Germans - they might very well have retreated if they couldn't actually "win".
I place a lot of the blame on the Miracle at the Vistula, combined with Poland overreaching herself in post-WWI. A smaller country might very well have been easier to defend - and Poland certainly didn't help herself with making enemies out of many of her neighbours. And of course, it certainly didn't help being in the middle of Russia and Germany!
