Well, I suppose it would have had a harder time easing into democracy than the dictatorship did.
You look at the first thirty years of the nineteenth century, and France is under constant strain. Thirteen coalition wars meant a massive drain of blood and treasure, even though the French won most of them. It was always easier to put off constitutional reform and let one man make the necessary decisions. That's the key difference between the French and, say, the contemporary Czarists. The Czar could excuse autocracy by right of blood and divine right. The Consuls- Bonaparte, Bernadotte, all the rest- excused autocracy through necessity. And even then they disguised it with the Senate and Assembly and the Prefects and what have you.
By the late 1830s, those crises are over. Germany is unified, but has formally forsaken all claim to French territory in Alsace and Lorraine. Ernst Augustus's Britain is well on the way towards the civil war that will make it one of France's brother republics. Yes, France no longer formally governs northern Italy- but the Lombard, Savoyard, Venetian and Tuscan republic are all in its political (and more importantly, economic) sphere. The Hapsburgs are too busy trying to put down their own nationalist revolts to think about the French, and in Constantinople Paris has a stout ally in Mohammed Ali.
So you have the space for political change in France. By then you have the best part of three generations who have fought at home and abroad for Freedom of the French people. You've got brilliant young agitators like de Toqueville who know how to speak to middle and upper class property owners without sounding like a St-Just.
Most all, you have a First Consul who is old and lacks the fire of his youth. Soult was a brilliant Marshal, and a good First Consul- but he was an old man in 1839. His only real base of support was the army, and credit to the man, he didn't want to govern at the point of a bayonet.
It was elegant, really- no need for a second revolution. Just six months of laws passed in the Senate and Assembly slowly handing back power to the legislature, and the stunning idea of when to hold the elections.
I know Talleyrand died a year before, but I'm sure that he was the one to suggest to the Neo-Girondins in the Assembly when to have the great referendum that gave France back to its people (and, quite by chance, the men who drafted the new constitution.)
July 14, 1839.
If there's a greater, more optimistic date in the history of democracy I don't know it. What was it that Dumas said about the President having the loyalty of all France and an obligation to all of France?
"All for one and one for all!"
