Can a demon be turned to good through hypnosis?


According to this article: https://forums.giantitp.com/showthread.php?410846-The-Redeemery-Saving-Souls-for-Good-and-Profit-Work-in-Progress it is possible to turn a demon other than a "demon lord" to good by summoning, binding it, and over time, using hypnosis to consider the tents of "good" and slowly changing it’s alignment to good…

There is presence as there is a lawful good succubus paladin…

What I would like is a further breakdown of weather it’s possible to do as the author pundits, using official materials available to 3.X
