It is difficult to say.
Your idea doesn't really work though, you have to take into account European Topography, look very closely at the countries you're suggesting the Germans traverse in order to invade the Soviet Union.
First off, let's analyse what actually happened when the Germans invaded the Soviet Union, Soviet Intelligence knew about the German Buildup, but Stalin didn't believe Hitler would actually break their pact and ordered nothing be done along the frontier to offend Hitler.
Even in the first hours of the invasion, he refused to believe it was real and subsequently apparently suffered a nervous breakdown not long after accepting the truth. But all this is with the benefit of hindsight and wouldn't really occur to a German Military Planner.
Had the Germans attempted to traverse the Carpathian Mountain Range in order to not invade Poland... This would have given ample time for everyone to understand what was going on.
German Military Leaders thought Hitlers plan to invade the Soviet Union was pretty damned insane... But they knew if they were going to have any hope of pulling it off, they needed to deliver a fast and effective knockout blow or else Winter would set in and they would be unequivocally ****ed and the Soviets superior numbers would grind them down.
The flat plains of Poland were the only way one could invade Russia effectively because of the way the Panzercorp operated.

The entire campaign was a simple question, could the Germans superior tactics, technology and element of surprise, deliver the knockout blow against Stalin before his superior numbers could grind down the German war machine.
And because of many, many factors... Too many to list here the latter turned out to be true.
On the question of England and the British Isles overall, I recently watched a very interesting video I'll link here, essentially it details that in fact, the Germans NEVER had the capacity to invade the British Isles, the Kriegsmarine would have just never had what it took to pull it off.
Feel free to fire back, I LOVE THIS STUFF.
