I am not enthusiastic about any topology that divides up the passband for processing then re-assembles it. I will not argue in favor of any one approach, but would not summarily dismiss the SVF because of how it acts with both poles tuned exactly the same. For a practical division of the entire frequency range into 3 bandpasses I would probably spread them apart. I repeat I am not arguing in favor of this one approach, just that there may be a little more to the analysis.
I am just scatter shooting out different possible topologies that might be of interest for people to think about. They can't all be winners, and I wouldn't expect generic schematics to be usable without alteration.
I recall the sound (ugh) of FM radio stations in the NYC market back in the 70's-80's when they experimented with not even very good loudspeaker crossovers (only 2 or 3 pole) in front of separate compressor/limiters, then summed their outputs back together. At least the later dedicated multi-band FM processors were a little kinder to the signal.
I recall several times being surprised by how different the vinyl sounded from the severely squashed radio versions we had first become accustomed to.
