as part of the plausible-implausible ATL im working on, france wins the napoleonic wars and occupies the former HRE. like many elements of my ATL, this is of course subject to change since im still working on it, but my question is basically this: what parts of OTL germany and the low countries could france conceivably and plausibly conquer during the 19th century (not necessarily during Napoleon I's time) and later annex as provinces of france? important changes to the timeline to keep in mind for this is that napoleon didnt invade russia when he did IOTL and he wins at waterloo, and then tries to invade britain but never succeeds thanks to the royal navy
