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.
I'll keep digging for a hemispherical layout though. Still not found a single example yet.
