Thin wall can work very well for mids. That's what the BBC developed it for. It moves the main box resonance below the voice region but into the bass region. As a radio station they were very concerned with the voice range. It doesn't do as well in the bass where the cabinet tends to ring more than a more rigid design. But most more rigid boxes have a main resonance right in the voice area. But everything is a trade off and you pick your compromises.

Would it make sense to make a speaker box where the mids are in a thin walled cabinet, and the tweets and low are in thick walled sections?
I don't know. I've thought of it. Genungo brings up a possible problem. The colorations of the boxes could be low but different. And differences often stand out at lower levels because of their contrast. A good friend who was a superb speaker designer preferred to use drivers from one company because they usually had similar signatures. But I think it's worth a shot.
A thin-walled cabinet radiates sound slightly differently than a relatively inert one does, I'm sure. Coherently blending the sounds of three different drivers in two different types of boxes might require some "fancy footwork" on the part of the speaker designer. Or so I'd imagine.Maybe this is why we don't see Harbeth (and others like them) trying to do anything like this?

Nothing ever is! :).
I guess it's true that if it were easy, then everyone would do it. I envision a three part speaker box but just picturing it, even assuming it works really well, I can see the cost of production would be very high. Furthermore, taking that into account, the "cost is no object" six figure speakers would probably be using it and I don't see any of that in the audio porn pictures.
Well designed interior bracing and deadening might approach the best of both worlds.
