Joystick support via SDL2 library?

Yes, I tried that some time ago, but if I remember correctly I had to build SDL myself with static linking support. Only then will the switch in the build file work. You should be able to use the .dll and .lib I included in this commit: Link SDL statically to avoid need to copy dll to output dir · SamPersson/UEJoystickPlugin@4e15a01 · GitHub
