What can I do to make the pi boot faster on raspbian stretch lite?
You can use raspbian stretch lite card to use the software but you can start only your custom script without anything else running.
There is linux kernel parameter init=/path/to/your/executable so you can just run your code directly as a first thing at boot time (shell script, python code,..). So your code can scan usb devices, mount filesystems, copy what you want, unmount and shutdown. It may be a bit tricky since nothing is set up for you at boot time, but there is really not that much needed for doing what you want.
