Don't be pissed about me keeping you in the dark regarding the ribbons; your comments elsewhere on the Nolas and ribbons in general had me loathe to make any recommendations. I think we may have very different tastes in terms of treble reproduction; I like my ionofanes, for example…

…and I do not think I ever heard ribbon-based speaker where I found the HF were appropriate. What I hear in ribbons is a constant presents of tacky glycerin-ness and this HF artifact is equally present in each HF sound, in any orchestra, in any instrument, in any singer, in any recording…  Also, each ribbon sound that I heard has very compressed in upper MF and had VERY low “transient babble-ness” in MF… However, I have to admit the any ribbon speakers that I heard used ribbons well into MF (2-3 channels or 4-cjakls with slow upper MF drivers). During my experiments when I crossed ribbons at 12.5kHz with 12dB an higher then the “MF transient babble-ness deficiency” was not auditable and the “glycerin-ness” become practically undetectable and… almost… beneficial…. I never heard high sensitively full-range horn installations complimented with ribbons…

… but more to the point, I have not not spent much time yet trying to integrate a tweeter with the S2s, which is what this all about.

Actually the integration is not a problem at all. Since I summarized that a tweeter must NOT be a horn then pretty much whatever I tried works very nice form the integration point of view. All tweeters that I use in par were compression drive and it was I feel a mistake…

The guy who runs RAAL has made a custom, multi-ribbon dipole arc of adjustable curvature looking exactly like what you want (save perhaps for diplar operation). There was a picture of it here:

I can’t see the pictures. What I was thinking to connect the ribbon’s array in series and drive them with one custom better Bad’s transformer. Or perhaps if it were I would say .3R ribbons then 5-6 drivers would make a couple Ohms and this impedance would be possible to drive by a dedicated HF channel with a special OPT, eliminating that, perhaps compromised, China-made transformer in the each tweeter… What do you think?  It might be an interesting project….

Anyway, I will try and get some measurements of my G1s for you to see what the sensitivity is like relative to some references.

Thanks do not forget to mention were I can fish them for 3 easy payments of 19.99 per driver… :-)
