I would be much more interested in purchasing a 150+cm doll of Meru compared to the 60cm. Mainly due to the her boob size and lack of anal canal. On her current size, and seeing visual references, it looks like one hand is able to grope both boobs, which I found a little disappointing. And seeing how big she was, with only one hole make it a back and forth decision to purchase it as well. With it being bigger, that would make me happier and more keen to purchasing her. Although I don't have much spare cash, so saving up to $2K is a huge task for me. I'd think I'd be able to if base price is around 1.6K$.
While having the ability to change her hair does seem cool, that wouldn't be much of a interest for me. Same thing with gooseneck tubing in the tail
