Hmm, well there is a running thought that since there are Four Mirrors of Lucifenia, each mirror represented a Kagamine. For example:

1: Waiter

2: Irregular

3: "Female Servant"

4: "Male Servant"

But I pretty much chucked that theory out the window since the Servants have nothing to do with Vanity...or so I think.
