What if Pope Pius IX accepted Napoleon's proposal of December 31, 1859 with respect to the question of the Papacy's temporal power?

In return, all of the Catholic powers (France, Italy, Austria, and possibly Spain and Portugal) would guarantee the Pope's territory in Latium, including possession of Rome.
