The POD I have in mind is that both Charles the Bald and Louis the German live a few years longer than they did OTL, solving the conflict they had at the end of their lives with a treaty that would've given West Francia the imperial title as well as Italy and Lower Burgundy, while East Francia would've acquired Lotharingia (Upper Burgundy could go either way). This would form an HRE-like political situation in France as Emperors would have to focus on Italy rather than being able to consolidate their holdings. I have two questions regarding this. First one is if this is plausible, and if not, how this POD could improve. Second one is the big implications for a move like this both domestically and in foreign affairs.
