A near ultimate challenge I've developed: get Marie-Thérese Charlotte, Madame Royale and only surviving child of Louis XVI and Marie Antoinette, to marry the future King George IV. How could Madame Royale get to Britain, single? Would see convert to Protestantism or would Parliament have to pass a law allowing for a Catholic Queen? Would the British try to claim the French throne for a third time? Would having his niece as future Queen of Great Britain and Ireland help Louis XVIII and Royalist cause? Or am I crazy and this is complete ASB?
