Thank you to all who replied to my post. Special thanks to Fons, Jörn
and Fernando who have suggested practical starting points.
I will make some calculations and decide on what will be most
practical for my experiment. I will report with my successes (or
failures).
Many thanks!

I'm not sure how to answer. What other techniques did you have in
mind? The reasons are several: I understand at least to some extent

Thanks Archontis, that is very useful. I'll try that, it seems to
corroborate what I had in mind initially. What's the worse that can
happen, right? :)
Thanks for the help!

Hi Martin,
HOA are not limited to icosahedra or only uniform arrangements (which exist
also beyond the 5 platonic solids). It would be very hard to claim them
flexible or universal if that was the case. Uniform arrangements though
simplify decoder design significantly.
As I mentioned you would
Out of curiosity - can I ask why you want to use ambisonics as opposed to

Plan A is more or less my backup. I'm fairly confident that I can get
that working. For my needs the verticality is more important up than
down, I would say, but it's a good point that the amount of complexity
might make it a better option for my plans next week.

Hi Martin,
one note on the arrangement, as far as I know, traditional ambisonic decoding
won’t work on hemispherical setups (due to the partial coverage of the sphere
by the speakers). You may have to use more recent/advanced methods to get
decoding matrices, such as the energy-preserving ambis
and floor as the
supports.
