Interesting question. They're both members of the same complex...pairing of different species within the same complex (for example, percula with ocellaris) has been done before. I have heard that the pink skunks are more passive than other members of the skunk clownfish complex, so it's possible that they'd be vulnerable to being picked on. I've never heard of this particular combination, but I suppose it could work. If you try it, I would get captive-bred fish, and also try to make sure that one fish is bigger than the other, so that the issue of who is dominant gets settled quickly.
