Hmm. Well I understand PiJe, and that one could learn from both Te and Fe processing, but they'd still be antagonistic. I suppose as long as Ni is your most differentiated function it wouldn't matter much, but still, NiFe looking for thinking to complement Fe seems like it would come from Ti not Te. I'm making an assumption there, but I'd see it as similar to how Se (obsessively) complements Ni.
Projection as I used it meant the process of applying insecurities and other psychological content onto other people, this is what would make it childish and naive, being too eager to overestimate others and objects, and then underestimating them to rationalize cognitive dissonance.
This forum is full of mostly JiNe(INxj) and NiJe(INxp). Do you notice the Ti aversion when you come onto INTPf?
