Aachen has definitally been considered, as it was the Charlemagnian Empire, but Luxembourg has already been made out (through the story telling) to be a second capital...rcduggan said:Nationalism was not fated to happen in the 1800s, it was a byproduct of the French Revolution. As the Kingdom of France will be significantly stronger in this AAR and thus more wealthy, the treasury won't be bankrupt in the late 18th century. So there won't be any French Revolution, thus no nationalism, and thus not a huge threat to the breakup of your empire.
If moving the capital, why not to Aachen?
Also, if it is not France... it will be someone else... such as Spain...
