Yes, it would be possible for the module to ramp ettr settings. Personally, I don't fool with the SNR limits. I usually hit my exposure limits at night anyway, it must not be very dark where you are
Bright lights, big city . I'd imagine that changing SNR limits would be useful, for example, when doing a day-to-night timelapse of New York (not that I live there, nor is my city *that* bright, but there's plenty of artificial light here).

Uh, last time I checked there's only 14 bits of data in a CR2. There's no benefit to using 32 bit in AE. 16-bits is more than plenty to fully represent every possible value in a RAW file. (If you use a 16bit workflow in AE, nothing will be clipped that wasn't already clipped in the original RAW file, 32 bit is unnecessary unless you're actually doing HDRI and have HDR merged 32 bit TIFFs or something that you're running through my script, in which case you should be able to get 32 bit output into AE just fine)
I know Canon CR2 only has 14 bits, but even so, there are advantages in working in 32 bits (after all, even the Red Epic's sensor is only 14 bits too, and people in the film/VFX industry work regularly in 32 bit float). The advantage is not so much in the "32 bits" part, but more in the "floating point" part. Working in float gives your software more precision when applying color grades, and allows you to stack up color correction tools non-destructively, even if the original source material is less than 32 bits.
Anyway, since I prefer to use the grading and keyframing tools in AE, what I'm trying to do is to import the full dynamic range of the original raw into AE, preserving detail in the highlights so that they aren't already "pre-clipped" when AE touches them. Stu Maschwitz's recipe is designed precisely to do that. I'll post here with further updates when I start porting your script to AE.
