I presume that you are wanting to modify the camera firmware used for jpeg images, since it does not do any of that stuff for raws. I have not heard of anyone being able to modify the firmware to add lens data, but it may be possible.
Adobe Lightroom can be setup to apply a correction as the file is imported, and supplies tools for a lens owner to make their own files when they don't like any pre-made ones. Thats about the best I can think of.
