"...she has become a V4 add on and is not even remotely as lovely as the original ..." 

That's pretty much the way I felt about Aiko 4. Aiko 3 however had/has a ton of support. The Girl Mk. 1's support paled in comparison. The Girl 4 may not be quite the same girl as the original but she still manages to express the sassy, toonish vamp spirit in a unique way. With the possibility of better support and the tremendous flexibility of the Victoria 4 morph system, I'd say she's a nice addition.
