It's funny , but I did the opposite and put a longer clip off a Kiwi 4 onto my DF2 .
I agree that a black clip would be a great idea , but it would need to be the proper type of finish like what is used on the Tiawan clips .
My GB 1 clip still looks likes it new even after a lot of abuse , my Delica clip started losing its black after the first day of carry .
