Would Bourbon France allow the screwing of Saxony? And what was happening with the former archbishopric-electorates of Cologne, Trier and Mainz?
The lands of Cologne and Trier went to Prussia IOTL, while Mainz went to Hesse-Darmstadt (for the most part at least). Considering that Napoleon effectively annexed all those lands and restoring ecclesial states within Germany just wasn't considered and seeing how the fates of Cologne and Mainz IMO are set in stone... That might allow the area around Trier to be considered to go to someone to counter-act lands being given to Nappy's respectable relatives (Murat & Beauharnais, essentially), however giving that land directly to them seems like a bad option because it'd be too close to the French border.
