• it's much easier to scale up than to scale down
• a PS4 system with the same hardware design (for 100% compatible) shrinked to 7nm would probably still need up to 50 W
• such a shrinked 100% compatible device would still be much bigger than a Switch and need much more battery capacity
• for a less powerful "720p PS4 handheld" EVERY PS4 game would have to be patched or reworked extensivly 

Which is why I suggest going with a new chip, rather than take an old, inefficient, power hungry design like the Playstation 4 SoC and shrinking it to 7nm.
You can still retain 100% compatibility with a newer chip design you know.

* For 720P though... If you have a 720P display, the games can still render at their original resolutions and super-sample them downwards.
I would much rather a 1080P IPS display at a minimum though. 720P is disgusting regardless of screen size.

And that's one of the reasons why I think it would be easier to make a portable or hybrid PS5, having such version included in the range since the start (or at least planned since the start even if actually launched later) would solve many problems, dev tools should take it into account and produce games that can scale seamlessly between at least two graphics levels (a third level for premium home units could be added too, and the most flexible engines could let gamers choose their favourite tradeoffs between resolution and frame rate).
