WI Richard the Lionheart or John Lackland marries Douce II of Provence

[kasumigenx]

I know that Douce II of Provence died when she was a Child but what if she survives and either marries John Lackland or Richard the Lionheart as King of England, would this result in an Angevin Occitania or Philippe Augustus will try to stop them from trying to claim Provence or can they claim Provence from the crown of Aragon in the first place?
