Yeah, that is some serious stuff. I was going to say can you make an analog - use as much of the technology as you can put into a 5k set of speakers, but reading through what Beveridge does and how you describe what is being done, it doesn't sound like anything is 'normal' or can be done cheaply so maybe there is no 5k version possible.
But Innersound somehow found a way to make the Isis! So... Something can be done!
There is a thread that Von Schweikert may not do their lower-end stuff (could be bad Rumor) - fwiw I really think these companies should keep doing this. And the Isis was eventually dropped. Makes us with what is actually a lot of money, but seems like a little compared to a lot of this stuff, feel like we can dip into the super-high-end a little bit.
Don't forget, the Boxster saved Porsche! :)...
