I would take my clues form a study of successful long-term relationships. The official MBTI people commissioned such a study and saw how types survived in 25 year marriages. The most likely pairings of N types generally were paired with people with 1 or 2 letters different, i.e. similar but not identical. So, depending upon the goal flip one or two letters ENTJ, ISTJ, INFJ, INTP, ESTJ, ISFJ, INFP. For management, I might omit the P-types. And, with the -T (turbulent) I might go for just the 1 letter differences to minimize conflicts). Thus, ENTJ, ISTJ, or INFJ. The exact best choice probably depends upon the individual as all INTJs are not the same and the individual specifics here might make a big difference. I would also avoid another turbulent (-T) type to minimize conflicts getting out of hand.
