OTL Phillip II of Spain moved Spain's capital from the port of Seville to the landlocked fort post of Madrid not without pragmatic issues and protests and Peter the Great moved the de facto capital of Russia to a brand new outpost in a swamp called St. Petersburg.
Each of the above monarchs successfully did these things to augment their authority and their acts would have permanent impact on the above settlements.
In spite of many times professing to be proud to have been Corsican, I always thought it odd that Napoleon never attempted to make Corsica an autonomous region in France nor do much to try to raise its standing amongst the French and Europe in general.
Napoleon had no shortage of ego so what would it have taken for him to have moved the capital from Paris to Ajaccio and making Corsica the new 'Ile de France'? In addition to stoking his ego, it might have even made him better able to wrest control of the Meditterean from the British Navy by being able to have the capital city on a port and using Corsica for spiralling naval bases. OTOH, it might have also made Corsica more vulnerable to British invasion.
Any ideas on how it could have been accomplished and whether it could have been maintained after Napoleon's death?
