They can be renamed into still other names such as kcfoo for example.
On the other hand, I think renaming all that stuff is a very difficult even if 
possible task. You would have not only change all the localization and 
filenames, but also much of hard-coded stuff and a lot of third-party 
software (of course if you do not want to drop compatibility with all that 
software).
