It's a cool idea but I haven't explored this in detail so I don't have a good answer. I haven't touched PHP in 2 years but they have a new feature which might achieve some of those design goals you mentioned:

https://www.php.net/manual/en/opcache.preloading.php

> preload.php is an arbitrary file that will run once at server startup (PHP-FPM, mod_php, etc.) and load code into persistent memory.

It's interesting to me, because in a big ecomm framework we were getting 80ms PHP page loads, with something like preload it could probably be moved down to 25 or 30ms.
