Hi Martin I've done my dissertation based on how to practically tell a story using only spatial audio. You can check out my full paper here https://www.academia.edu/33968228/Practical_use_of_Spatial_Audio_for_Storytelling comprehensive of tools used, psychoacoustics aspects and so on. I did avoid binaural tho, I prefer a multichannel loudspeaker system to reproduce something like this.
You can create convincing soundscapes combining simple ambisonics beds and groups of sound particles (check out the software Sound Particles, free for one year for students). Reverb is so important in this case, I used Spat for Max for the spatialisation, combined with Reaper for editing. How many people are going to experience it in once? Have a quick read to the paper and let me know, I'm more then happy to help.
