How possible could it be for Louis XIV to unite France, Spain, Portugal, Naples, Holland, Belgium, and Sicily if he was victorious in the War of Spanish Succession? The concept of such a superpower is mind-boggling, rivaling the power Rome had over Europe 1000 years ago. But the question is, could it even be stable? I mean, it seems like after his death. The empire would be so big it would collapse over its own weight. But if it survived... Oh man Louis could easily claim the title of emperor and just conquer all of Germany and Italy!
I'd love to see a TL of that!
