RSo,
Cute, but no cigar. Besides, I have too much respect for the memory of the Rebbe, zt”l to say he was a navi, since nowadays only a shoteh can have prophecy.
It should be noted that when nevuah existed, a Jew who experienced prophecy in Eretz Yisrael could then experience it anywhere else in the world. Classic examples are Yonah and Yechezkel.
