The Von Schweikert Unifield 3 uses a similar concept. I attended the 2009 RMAF with Albert Von Schweikert who was featuring the Unifield 3 at the show. He called it an augmented full range speaker. The full range speaker he employed was a 5” Fostex driver. It was crossed over to a 7” woofer at 100Hz and a ribbon tweeter at 8kHz. It is a wonderful sounding speaker which has all the benefits of a full range speaker with bass and treble extension most lack. I often played with the idea of building something similar with a larger woofer (maybe 12”) to give more bass extension and impact.

A supertweeter crossed high is only detrimental. Crossing so high causes severe vertical lobing issues and even more unpredictable and disjointed dispersion.
The point of the proposed design is to have near-coaxial coherence in a large woofer 2-way, without having to add a tweeter, or a coax driver, as all DIY coax drivers (SEAS etc) are compromised vs the proprietary ones vs Genelec and KEF.
