"Conversion" is certainly possible.
Probably not for everyone, no (and that is fine!!)
The whole basis of change within society is that people begin to feel differently as ideas and knowledge and exploration comes to them.
People convert their religions, which is a fundamental value system for some people.
People become vegetarian.
People change who they vote for based on their changing beliefs and values.
Economic systems change when people believe there are alternatives.
Human beings are capable of significant, ongoing and phenomenal transformation. A fact that never ceases to amaze me !
