I did try to work with an hex editor and KN7000 files in the past and couldn't figure it out. It's more than just changing the heading of the file I think.
I've always wondered why some programmers who have created very good KN7000 applications like the "SD-TechManager" for instance, never thought of a "KN7000 or KN2600 to lower KN keyboards" file converter.
maybe Alec could help us on this. . .
