Color change

I got this tattoo about 9 years ago. I still like the design but I think the artist didn’t do a very good job with the colors and now that they’re fading I was considering to get it re-colored and I’d like to turn it in a completely B&W tattoo. What do you think of this idea? Would it even be possible?
