The genealogy of The Twelth Imam

The Twelth Imam, future Saviour of the Shiites is a very interesting character. His mother, is maternally reported to be a direct descendant of Saint Peter, which automatically makes him Jewish by Judaic rabbinical law. The mother's paternal ancestry is claimed to have been traced back to a Roman emperor; we have now link between The Twelth Imam and Rome, practically on a genealogical level.
And his father, is reported to be a direct descendant of the Prophet Muhammad, through Imam Hussein, while the latter himself is said to have married a daughter of the last emperor of the Sassanid dynasty of the Persian empire; thus making The Twelth Imam Arab and Persian in origins paternally.
Thus, in The Twelth Imam, we can find a perfect ancestral union between the Arabs, the Persians, the Romans and finally the Jews. Paternally, he is an Arab by direct ancestry and amazingly, maternally The Twelth Imam can be considered Jewish if the Jewish ancestral law is taken into account. In Judaism, a person's Jewishness is taken through mothers, not fathers. And a person is still considered Jewish even if he or she embraces faiths other than Judaism.
Is it possible then that The Twelth Imam of the Shiites will simultaneously make claim of being the long awaited Moshiach, Saoshyant and Christ of the Jews, Zoroastrians and the Christians respectively?
