Let us know how it goes ... 
I am hesitant to embrace the idea that a vast difference between the output of various sensors is the reason.
I understand that more than a few cameras use sensors that are quite different from the sensors sold by the big 2?, 3?, or perhaps 4? camera manufacturers. Still, the reasoning that these varied sensors preclude the development of processing software would pertain to all general-purpose RAW converters regardless of the goal.
I imagine we could all agree that for the most part the sky is supposed to be "blue", or orange, or pink, or grey... and it is often found at or near the top of the frame.
I do know that not every camera model's RAW output can be converted by any or every RAW converter.
I don't know of any camera and RAW converter combinations that get the basics terribly wrong if they do support the camera model.
Anyways, I don't want to, nor did I come here to disagree about why there are no converters such as I am asking for.
I have yet to confirm that none exist.
If, indeed, none exists, I may still feel surprised, but I will not dwell on it long enough to argue a case that such a thing should exist.
I am simply trying to elicit recommendations for a Digital Image Processing package.
Out of 10 replies to my original request about software, only one has included a suggestion. For that, I am grateful.
Thank you.
