Patience.. lol. As far as I know, there are no third party applications that will read a 1.2+ tsi file from Traktor. If you do find one however, please let me know!
As far as modifying your tsi…always create a backup (I usually add the date, and revision changes in the file name)
I also find that once I change something, it is a good idea to write a brief description in the comments section about what that particular command does. That way when it comes time to change something around, you can always just group your midi commands by description, making your life much much easier.
