this is the exact reason why I will not ever release the updated wkKeyRemap. if such ridiculous "rules" didn't exist, there would be no problem. now we have to write platinum crutches to the already working code in order to satisfy your "needs", which is something beyond the initial inspiration for the module creation (in order to block a key, there have to be more deep researches done, and that isn't possible because Kawoosh simply won't want to look into it). note that wkKeyRemap uses native W:A's keyboard code, without anything external, which is why it only works during the gameplay without affecting chat, and doesn't depend on anything besides W:A. in fact, if WA ever had a built-in remapper, it would be internally 80% similar to the one implemented in wkKeyRemap.
if out of sudden there pops up a desire to keep the module's development, then the module will be released and everyone will be happy, otherwise no, no way. or, you can actually make your own... the keyboard functions in W:A aren't as hard, an average reverse engineer will be able to manipulate them to his will.
