You may not like what I'm going to say....then again, you may.
(I have no idea of your budget nor how extreme you want to take your speakers)
Having heard what I've heard, here's what I'd do (and in fact, AM doing with my LaScalas)
Buy a Klipsch K510/K69 ensemble (2" throat horn lens and driver)
Get an active crossover and go active with the speakers, taking them to a 2-way format.
If you like the sound, you could sell the ALK's to recoup some costs. If you became committed to the sound, you could sell the other drivers & horns as well (and plug the holes)
The K510 would sit on top of the speaker, I do not know if it would physically fit inside. I know you'd have to cut the front of the speaker and I personally would not want to do that.
(I am however, going to surgically alter one of my three LaScalas and do just that.... put a new motorboard on the speaker, make a cutout and insert the 510 inside the tophat.)
This is a Klipsch product, the 510 has been engineered but for, the specific crossover point. I (and others) could provide the PEQ's of going active with a LaScala but I couldn't give you the profile for the Cornwall (though Klipsch has told me it should work)
Follow Ups:
I agree with Richards recommendation for a set of K510 horns. The K701 is a small tired old horn which distorts too much and is not large enough for the task at hand. Best regards Moray James.

Yeah, Fastlane Audio has some beautiful horn designs for the Gen 1 & 2 Cornwals and Stack-on units for the Gen 3, La Scala, LaBelle and K-Horns. I think I'm going to experiment more with the horn treatments and settings (ALK provided for 6 mid-range and tweeter attenuation points and jumpers for two-way operation) I will exhaust all these options before I start in on irreversible changes to the cabinetry, as these speakers are less than 5 years old. I am intrigued by the B & C horn driver options, but I think getting the horn right is the first order of business.
Thank you for your advice.
May you have a Merry Christmas,
Best Regards,
Steven Manseau
