We can't boot from the USB3, since the drivers are not available
until the boot is done (i.e. the kernel loaded).

I would try the first route. I currently don't see any advantage to
the second (in both cases you depend on your USB2 drive to boot).

I proposed first to try a Debian live or installer on your USB2 to
make sure the kernel coming with it can talk to your USB3 hardware.

For example: if you start the Debian installer off the USB2: does
it offer the USB3 drive as one possible install target? In that
case the drivers would be there.

I haven't got a ready-made instruction manual per se, but we can
take it from here with the help of others :)
