Hi Alan,
I'm not certain that editing the headers will do the trick. The only way to find out is to try it.
I've had some luck doing this with a program I wrote to allow my PR54 files to play on the KN7000. I don't remember my PR numbers but I think the PR602 is closer to the KN6000 which would mean that the styles are usually not compatible even with header changes.
Best Wishes
