I recommend you visit the website of the 2nd co. I mentioned. "Total Spectrum" as they call it, captures UV, visible, and near-IR light. They say it's used in Forensic Science and Astronomy. The "beauty," in my opinion, is that one "should" be able to apply external optical filters to screen out certain parts of the spectrum. However, they report that when external IR filters are applied, the toll exacted on the live viewing display is such that it becomes difficult to see the scene of what one is composing.
With reference to your color IR film "plight," with respect I don't believe that's at all a problem for an IR camera, so long as similar wavelengths of light are detected by the sensor.
I noted that if I was to get my Sony a6000 camera converted, that co. cannot convert it to Total Spectrum, probably because the sensor isn't of that type in the first place.

I have read your reference today and learned a great deal on this subject. I am beginning to understand the benefits and limitations of Digital Camera-IR photography. Some 30 years ago, I photographed the remains of color on ancient Greek statues and was able to capture some of the original: what looks to us dark red today turned out to be mostly golden yellow but also either blue or green. I have been hoping to duplicate this process using modern equivalents. Total Spectrum -with or without filters- looks very promising.
