Interesting... but I have to disagree. Since none of the girls are actually visually shown, mothy doesn't have to reference them in any way but name. As a result, a character like Rindo, while obviously referencing Kagamine Rin and Riliane, doesn't have to be a Gretel character or even look like the Vocaloid she references in the same way the Rin character in Tailor Shop doesn't have the same color or apparent connection to Rin and Gretel either.

We'll see though... It is thinking outside the box for sure. The only characters I think are connected  to future characters thought are those that have obvious connections: the four main harem girls, Hakua Netsuma, and maybe Lilien (depends if she is the ancestor of Lily Mouchet).
