What do you think about Cynthia Caroline?

I love the name Caroline, but probably won't be able to get to use it, since I want to use Alexandra Kaitlyn, Cynthia, and Holly Danielle before getting to any other girl names. So I thought, what about changing Cynthia's middle name to Caroline. What do you think? Nickname would be Cindy or Cyn, preferably not CeCe. Thanks, guys!
