i would not do that and looking at the price of a VPS
where you can run real cronjobs i don't see a reason

because it's likely unsecure in many situations and you open a can of worms
because it fights with server configurations and ressource limits
because it fights with timeouts and what not
that's why possible ressource intensive and long running things
typically are not done within the webserver process

but don't start a session because a random GET parameter leads
in two options, none of them makes sense
* your request does anyways not work because the CSFR
* you disable also CSFR if the param is given which is not smart to say it polite
