I'm honestly not sure why you'd want to deconstruct this back to default and then rebuild it.
All the systems are in place and actors use new advance and retreat poses for moving towards and away from enemies.
Additional poses must be called as if they're within the default listings of MZ, however their uses can be altered. If you look in the notes section within the plug in manager there's a full listing of them there .}
Hope that clears things up.
