I have a slow and big hdd and a fast but small ssd and want to test
the following setup but don't know if it's possible.

This doesn't make much sense. If you want to speed up your HDD by
using the SSD as a cache, you can set up one of the numerous
block-cache systems available for Linux: bcache, enhance IO,
FlashCache...


I know these systems and tested them but I also wanted to try the above mentioned setup. That doesn't seem to work though.
