Gosh yes; obviously Obi-Wan sleeps with Amidala and begats Luke and sends Anakin evil (and Amidala was in fact the Chosen One and passes that to Luke), and equally obviously Amidala is Sidious' agent in turning Anakin evil.
You can't disprove any of it from what has been said, so long as you write off half as what is said as lies and make a hundred suppositions of your own.
This is why I discount wild theories like this one, which is entirely based on the flimsy premise that QGJ and Sifo-Dyas died around the same time.
