Charlus,

As you expressed here this would be an End of life speaker project, and I am sure you will not fancy any other speaker once you start with this, even Vox Olympian etc. Yes it will take a lot of money and a lot of time, but you will have fun from day one, and thats what its all about.
IME the easiest part is the tweeter and high mids horns, the most complicated is the UBH and the bass solution.
I started my speakers thinking about the SA tweeters, had those then RAAL and a couple of other ones including old plasma tweeters...

So the first thing you will have to decide is on how you will play the melody range: in my system I use one driver from 115 hz up to anywhere from 500 to 1.5 khz. The high point depends on what driver I am crossing to. I have tried also several Compression drivers here with different results.
If you get the S2 drivers and Spherical horns follow Romys advice on filtering it. I guess you will buy new S2 drivers, used ones are almont impossible to come by lately.
Getting right just tihs range from say 100 hz up to 12 khz will raise the hairs in your back if done properly.
Once in a while you can add a tweeter and a woofer under this, play with the full system or just with the two main horns, or just the UBH. Once you get this even halfway, you will have a system that can take you to the end of life just like that, depending on the success of your other channels. You might add the tweeter your like and a woofer, maybe follow Romys old bass solution, maybe just get an Altec 416 in a cabinet for the time being, that will get changed a few times also.
Once you have this settled prorperly you can add a new driver, from 350 to 1.5khz if you feel you need it, trust me you might not think you need it depending on the kind of music you listen to. Dont buy this driver just yet.
And there is also the Infra bass channel, which is a lot of fun!

all the best
