Strangely, I was just contemplating a scenario that would achieve this in a round about way. Basically, France falls to a military dictatorship after the war that brings the Orleanists back to the throne. An uprising against the regime in the 1930s triggers a civil war, which ends with a negotiated peace that is heavily influenced by the other great powers.
The final outcome is that the military surrenders power to a moderate democratic government. On one hand, the Orleanists are too associated with the old regime to continue, but on the other, Great Britain, Germany, and a still monarchist Russia are worried about the ramifications of fanning anti-royal sentiment by creating a republic, so a Bonaparte is brought in as a compromise.
I honestly don't know how plausible that chain of events would be though.
