United Israel, Messiah and Dynastic Marriages

Dr. Tabor makes a compelling case for the Jesus family dynasty using evidence from Talpiot to support his theory. In RAF he defines the primary function of Messiah as a "restorer of the Kingdom of Israel." If Jesus was a messiah, then he would have been totally aware of his function as Dr. Tabor correctly states. Is it possible then to conclude that the marriage between him and Mariamene would have been dynastic in nature, the forging of a "peace treaty" between two contentious tribes?
