Beside that it would be a nice addition to have something like a “clone-brush” in RT which Ialso would love to have.
From what I’ve learned so far there is no RAW editing software, which does manipulate the RAW itself. So everything you do inside any of those RAW editing software is always stored as “settings” for the program itself. So as long as you don’t prozess a RAW to tif, jpg, what ever you only would see the things you’ve done inside the RAW editing software. Those programs differ in the way they do things and therefore they store different “settings” and also the way they store those are different, different formats as pp3, xmp, dop and other and different places and ways as side car files, inside a database or even inside the xmp section of the image itself.
Well even - at least from my point of view - if you open a RAW file in which ever RAW editing software, you don’t look at the real sensor pattern, you already look at some prozessing this pattern into a more viewable image. Well at least I havn’t seen any RAW editing software displaying i.e. the Bayer pattern (scroll down to the first third of this article about zero noise, there is a pic of what I mean).
So my answer to your question would be NO, I don’t know any software which would manipulate the sensor pattern.
