There's a lot of mysticism about the Imperial throne, but just remember that Emperor Uriel Septim IV had no blood relation whatsoever to Tiber Septim or even to the line of Empress Kintyra, who were descendants of Tiber Septim's brother Agnorith. Since he was successfully crowned it seems that he wore the Amulet of Kings and ignited the Dragonfires. The same assumption applies to Emperor Pelagius III who was half-Altmeri and his son Cassynder who was half-Dunmer (although the modern Septim line isn't descended from this branch as so doesn't carry the same Mer blood). For that matter Empress Kintyra II had her ancestry disputed and it was claimed that she was born out of an affair by her mother. While this may be merely gossip, no one at the time seemed to be certain she was a true Septim by lighting the Dragonfires.

The Imperial line has a long and convoluted history and it seems as though Akatosh hasn't always been as concerned about the whole bloodline thing as events during the Oblivion Crisis would suggest.
