I don't know what was there to see in the link, but ZUN already did it. Though I don't think the Amusement Makers were holding him back; I think that he had his different moments. The one I noticed first was the relation between Yuka and Yukari; the two are almost the same thing, in fact, everything that Yukari is was already old long before she was created.
Some other stereotypes are similar, but as of now I don't recall any other example in which the characters are so similar.
