Hi. I want to "Throw this out there" and see what other people have to say, even if it's "You couldn't be more wrong." I freely admit I'm not a psychologist, so maybe I have no idea what I'm talking about, but I'm not fully convinced that the 8 cognitive functions (Ne, Ni etc...) must go in opposing pairs for everyone. To take myself as an example (although I doubt I'm the only one who has experienced this), hypothetically my Fe should be easier to use and more effective than my Ti. I think the opposite is true. In fact, I think my Ti developed earlier than my Fe, and I identify as much with Si as with Se. To make it a little less personal, there are probably very introverted types who tend to use their introverted child function more than their extroverted parent function, because introverted functions probably feel easier. Same with extroverted types and their extroverted functions. So, instead of functions always being in opposing pairs, wouldn't it make sense to re-order them as an individual, so that they reflect how well-developed your functions are? So, an INTJ might actually be more of an Ni, Fi, Te, Se in rare cases, to give one possible example.
