If the person expressed strong desire to adapt to a new culture, then I would do everything and anything I could to help them.
If they aren't totally passionate about changing their values, then I would help them find a new opportunity in a organization and culture that was more a match for them.
This is a tough challenge if they really want to change.
If they are anything less than totally committed to this kind of change, then it's impossible and you're better off finding someone who's a match for the culture and teaching them the skills.
