Each of the modules or types of modules you listed could contribute to your objective. To produce 'generative ambient stuff' I would also suggest Sloths and/or Diode Chaos. That said, Zadar+Nin and Morphagene would be my priority. I must say that they have today established themselves at the center of my setup when it comes to generative and ambient music, and in many other styles...
