If you're looking for a post Napoleonic PoD, you could try to have him pull something like Napoleon iii did IOTL.
Maybe someone super anti-austrian gets control of France so Napoleon ii is allowed to leave and gets tacit support from Vienna?He's gonna have to get out of Vienna to do that. AIUI, he was kept under pretty close surveillance by Metternich. Countess Camerata (his cousin through Elise Bonaparte) was the only Bonaparte IIRC that actually managed to slip under the wire during the events of 1830, but L'Aiglon didn't know who she was when she came up to him and kissed his hand (think she addressed him as "mon empereur" as well).

Napoleon I wins the Napoleonic Wars.
The Austrians were actually pushing for exactly this in the early stages of Vienna: having the Cohalition install a regency for Nappy Jr. and retaining the form of the Imperial system if limiting it's military power. If you can find some way to have the Austrians in a stronger negotiating position relative to the Brits: say, Prussia not effectively reform/recover an be "Liberated" rather than taking a prominent role, and this could easily come about with Le Emperor merely abdicating for his person rather than his dynasty.
Interesting would be bis relationship with his Cousin Louis Napoleon.Napoleon I accept the Frankfurt Proposals of 1813 and become Emperor of an expanded French Empire. He would die somewhere between 1820-1830 and Napoleon II becomes Emperor.
