Agreed with the others that this should not go into the engine (and this should also not really clutter up the Internals list), but if you have a real need for running different versions of PHP for different URLs, you could pretty easily set up multiple FPM backends (one for each version you support) and have Nginx map URLs to these. It would be a maintenance headache, but not the disaster this would be if it had to be maintained in PHP-proper.
