What would an ENxJ be like?

..as in interaction, his or her way of thinking, etc.

Do you mean stuff that's true for both ENTJs and ENFJs, or one that is both T and F? You can't have Te and Fe, or Ti and Fi as both your conscious functions, so you can't really be in the middle. You could be an ENTJ that's more dominantly F (uses inferior function Fi more than dominant Te), or an ENFJ that's more dominantly T (uses inferior function Ti more than dominant Fe), but can't have all four TF functions as conscious functions.
