Yes, it will take some trial and error to find a sufficient solution. Perhaps some situations can be handled with simple tools and others requires more precision. Great ideas on where to dive in.
I will primarily record outside for the soundscapes I am working with so it is also important it is relatively easy to handle in that situation.

Just an idea.
- I have seen people using the possibility of summing the IR's. This I guess would make the reverb less directional and cover the IR's of a larger area.

- In the Ambi Verb tutorial it says you should record 1 IR 2m from the emitter. Ex. Speaker on stage and microphone 2m from it in the audience. This could be a bit low resulotion imo.
The sweep file is only 7 sec, but otherwise I am thinking of sending a white noise signal from a recorder directly into the speaker and then pressing stop, to get a broadband IR signal.

- If I record 4 IR's (n,s,e,w) in the horizontal plane around the ambisonic microphone at a 2m distance and sum them. The convolution would then be a panned mono signal with an ambisonic IR.

Would that give the reverb a rough directivity during a convolution in accordance to this logic
