Any princess hooking up with a Joshua/Jesus figure could be considered a "Rahab/Mary Magdalene", including Mariamne II. As I said before, I don't think we can assume that the Boethian and Onias lines were identical. In fact, I'm pretty sure they were. Boethus (Mark Antony) was a separate lineage from Hanan/Onias coming down from Zerubbael in the Persian Era.
As Tim has convinced us, Cleopatra Selene is one and the bride given to Parthian Phraates IV/Herod by the Romans. According to Parthian tradition, she killed princes that were rivals to her son by Phraates and ultimately poisoned Phraates himself to clear the way for her son's succession in Parthia. Some think that her alter ego Mariamne II was disgraced by Herod for conspiracy, however I don't see the evidence for disgrace. Her son Herod Phillip remained in high standing both before and after the death of Herod the Great.
