Have you tried running 1D files through modern noise reduction, such as Adobe’s new Denoise? Based on the sample images in the archived link, modern NR will likely generate better results.
EDIT:
I tried it myself with a few 1D files that showed various degrees of banding. Unfortunately Adobe's Denoise doesn't fully recognize the banding as such and has varying degrees of success/failure at removing it. The stronger the banding, it appears Denoise recognizes it more as possible image detail and instead retains/enhances it.
Examples below - the first is an ISO 200 file with shadows pushed 100% and a crop of the upper right of the frame shot at 22mm with the EF 17-35/2.8L. It's the worst case I found quickly. The second example is ISO 800 but without dramatic exposure push. There's subtle banding in the dark area which Denoise fairly reasonably eliminates/masks, but not perfectly.
Would be interesting to see how Fred's old actions stack up against Adobe AI, haha!
Based on the old firmware files I have on file, the first image may have been on FW version 1.3, which my file dates to January 25, 2002. But the image was shot February 3, 2002 and I was traveling at that time and might not have risked a firmware update mid-trip. The second image would have probably been FW 1.3 though 1.4 I have on file is dated a week before that image, but again, I was traveling and not sure I would have risked an update the day before departure...
I tried a few more that should be on FW 1.4 and it's the same. There are instances where Adobe Denoise IMO interprets the banding as image detail, makes it more pronounced and therefore worse. It really seems to depend on image content. Regular luminance NR in Lightroom appears to be more effective with stronger banding examples, but destroys fine details elsewhere. It may be a matter of blending two versions of images to reveal standard NR in areas where banding is more noticeable.
