Would Saruman have been a reliable ally?

When Gollum being evil could serve good, though, not willingly. couldn't Saruman be the same? His "voice" is said to be cruel(?) and poisonous(use of words is not clear, hope you got my point. ). Not saying, Gandalf had to "trust" the Orcs, but they, with Saruman's help, could turn them against the Army of Sauron. Aragorn looked into Palantir and that was enough for Sauron's world to turn upside down. Perhaps, knowing they are going to destroy the Ring, Saruman would have betrayed them, sending his Orc-battalion to fetch the hobbits. For his own salvation, i.e. FREEDOM from evil, he might have come to good. If, according to Gandalf, Gollum had chances(very little)of redemption and survival, Saruman would have too. But, sadly his fate was not to turn good and understand goodness of Good side, and evil of evil side. He died like that. What a tragedy!
