I've been using this plugin for quite some time. Mostly to get rid of embedded fonts, but checking the option "Add/Replace metadata jacket" updates the tags in the jacket.
I'd rather use this instead of a conversion. My guess is that this plugin doesn't alter the epub as a conversion would - sometimes it could have ill effects.
