No, changing the preferences file certainly won't prompt the
preferences to be reloaded. You need to go through the preferences
system itself. You're essentially trying to change an open text
document's content in a text editor by rewriting its file on disk ...

I don't know if all defaults domains are available for
manipulation, but you need to go through the defaults system instead
of modifying files behind its back.
