Not a chance. There is a point at which one can turn back from Chaos. After becoming a Daemon Prince is not that point. Of all the Primarchs only Alpharius Omegon have a chance, and it's slim. For that matter it's not really possible to bring somebody back from Chaos corruption. You have to understand that it isn't simply some evil religion. The Chaos Gods have absolute power over their minions. They reshape their hearst, bodies and minds as they see fit, and can actively and immediately punish a Champion that displeases them. Unless you turn someone from the Dark Gods early there is no hope. After that point that person is less a servant of the Dark Gods, and more their possession.
