I have had thoughts about what a self-standing Dolby II or DBX II processor could do if hooked into/out of the recording loop with a projector.
It might create its own set of problems with regard to accurate playback 'tracking' of the processed sound track because of less-than-ideal frequency linearity of the projector, but since the units worked with cassette tape, it might be fine.
It is curious that no form of 'companding'(compressing/expanding) noise reduction made its way into a format that could really use the help, sound-wise. But there may have been reasons I don't know.

Been there, done that. DBX II works quite amazingly well. The trick is that you need a 1/3 octave equalizer, some reference pink noise on CD and a real time analyzer to "calibrate" your recording gear to that specific stripe. Once you set that up, you are on your way to recording near-CD quality tracks.

The "Dynamic Noise Limiter" System (Philips) could do a good job with all Super 8 prints and projectors because signal processing is only active in playback mode. I can imagine that Elmo used a similar system with the PCom. Of course, it's not as effective as Dolby.

Although it would not be the same as true DBXII, couldn't you pass the recorded signal through a cassette deck that has Dolby B option via tape loops? Placing this between the Pedro box and the GS1200?
I don't have any of this equipment at all, and I do not rerecord tracks. So maybe I am hopeless. Please do not confirm the part about hopless. LOL
