I feel a sort of kindred spirit thing with every NP that I meet. An Fi/Te commonality wouldn't be any more viable in my opinion than an Ne/Si commonality. All NP's "speak the same language" - meaning their primary mode of extroverting is Ne. I usually click with them right away. Even if they go off on some crazy Ne rant that I don't feel like listening to, I at least understand it and feel a "sameness" with them. With NJ's, it sometimes takes me a long time to determine if they're even N's or not, cuz Ni sort of stays under the radar - it can be hard to pick up on. I've thought many INTJ's were ISTJ until I really got to know them better. I've probably mistaked INFJ's for ISFJ's as well too. But, when someone starts Ne-ing, I can spot it from a mile away - and I usually laugh at or relate to what they're saying, at least on some level.
