Challenge: Have Napoleon lose the war, but instead of restoring the Bourbons back to the French throne, have the House of Bonaparte remain the emperor.

One possibility is to have Napoleon's son, who's mother was Austrian, Napoleon II become Emperor, with someone was regent until he was old enough, since he was at least 3 year old at the time.

OR

Challenge: Have Napoleon III remain in power, after the Franco-Prussian War.

One possibility, is Napoleon III isn't capture, and makes a peace, and wins the fight against any revolutionaries that rises up.

For the first one it might be possible to engage Napoleon II to a Bourbon heiress (there might be one running around somewhere)- this would make everyone happy and everyone not so happy at the same time.
 
Napoleon III manages to get British support for a neutral candidate for the Spanish throne. Franco Prussian war never happens.

Then challenge failed, as it explicently states AFTER the Franco-Prussian War. Of course, it never said he has to lose...

My idea though; have the Republican or Reds try to stage a coup in Paris while the French army is still intact. Nappy III is obliged to sign a bitter peace to turn around and crush the insurgency, and so the blame for the lose falls on the backstabbers and stains the Left politically so the Liberal Empire retains a lion's share of the population's suppoert
 
Napoleon can agree to the Frankfurt proposals. Another chance would be at the battle of Leipzig, where the day before the battle the French had a solid chance of capturing the allied monarchs.

Napoleon II has a chance, in case his Austrian grandfather has a clash with Louis-Philippe and decides it's about the time to press his grandson's claim. Or, considering that at various times the Eaglet was considered for the positions of king of Belgium/Poland/Greece, he could use these resources to press his claim if there is political turmoil in France, and the Bonapartists manage to make the move.

Napoleon III may not have succeeded in saving his throne, but his son could have brought the Empire back, having the British support and the Frenc being in disarray.
 
Have the Comte de Provence die before 1814. The Comte d'Artois with his ultra-reactionary attitudes and desire to restore an absolute monarchy would be far less palatable in 1814 and might convince the United Kingdom to support Francis II proposition of a regency for Napoléon II.

The problem with Napoleon accepting the Frankfurt proposals is that Napoleon isn't really the kind of guy to give up unless he is forced. Just look at his escape from Elba.
 
I'm not sure how you could pull off a successful Polish revolution in the first half of the 19th century, but it would be pretty cool to see a Napoleon-acknowledged Alexandre Colonna-Walewski in charge of an independent Poland.
