Ok, her come Jessi and SP3:

Out of the box and adjusted to match the Loomis head size, Jessi is a massive 6'0", while Stephanie is a "not really petite" 5'8".

Lets see what we can do with them:

I scaled Jessis legs A LOT shorter, as well as her neck.
Made her arms longer and her head larger. She ALMOST looks human now, but her strange knees and shins, as well as her hands still give her away as an evil alien Fembot (From outer space)  ;-P

SP3 is pretty all around perfect, especially her legs.
But I don´t like her overly thin neck so I still scaled the head up a weee bit and made the neck wider along the x-axis.
I´m also not that fond of her squarish hip shape, but all in all she has the best out of the box shape foor a TALL (!) young athlethic woman, while Miki represents the best "average" body type.

Posette/NEA and Judy/NeJa hold up pretty well, and with a bit of scaling and better shoulders NeJa looks pretty good.
IMO her shins need some work just like Jessi´s, but her knees are a lot better.

Jessi and V3 sure are the most problematic. Only a major overhaul or some loose fitting clothes can save Jessi.
(But to be fair, she by far has the best shoulders and I like her face)
V3 can be morphed pretty easily, but SP3 can do everything V3 can and has the more realistic bodyshape out of the box. She also bends much better.
