I don't know enough about you to say for sure whether or not you are typed accurately, but I don't see why not. You strike me as kind of a strange mixture of radical and indecisive, a great combo for challenging paradigms and causing transformations in the world. That also lines up well with NTP.
As for my own type, I decided on the following fusion:
IxTP/TPIx 5w6cp>8w7>4w5 Sx/So/Sp Solitary~Adventurous~Idiosyncratic
From what I've been able to tell thus far, it makes sense.
Enneagram 9, being 9II (i.e., double Intrinsic), would make an ENTJ appear more introverted, as would sp/sx (hence, formerly xNTJ).
Similar to how enneagram 6, being 6SS (i.e., double Systemic [i.e., ambiverted]), and sx/so (extroverted), make me appear more extroverted.
