Hey there GalenL,
While that’s a really interesting concept, it’s not what our Facebook Events plugin is designed to do. You’re asking to go from WordPress into Facebook, while our plugin actually pulls data from Facebook and puts it into WordPress.
You may be able to find a third-party plugin that can accomplish this, but it’s not a feature ours currently has or that’s on the immediate roadmap. That said if you wanted to make a request for it on our UserVoice page, we’ll definitely take it into consideration as we plan future releases.
