Would a portable PS4 even be possible from a technical perspective? Like even ignoring the issue with power is it possible to shrink the PS4 architecture down to a handheld? I feel like they would end up with a system that would still require a dedicated ports from the PS4 as opposed to playing it's entire library right out the gate like the standard PS4 or the pro so it would be less of a portable PS4 and more so a psp3

For now the Tegra chip is the stronger gpu+cpu and Nvidia has signed an exclusivity with Nintendo for at least 2 generations.  Sony will need to find a new hardware partner. 

Where did Nvidia sign exclusivity? Source?
