Anne Boleyn vs a different first wife of Henry VIII

What if Henry VIII marries Margaret of Angouleme and provides only daughters for him, what if he tries to dispose Margaret of Angouleme in favor of Anne Boleyn how would the scenario play out.
 
The fact that Margaret is younger then Catherine must also by taken into account. By the time Henry tries to have his great matter divorce Anne might have married already.
