I did a little experiment - I took the sideshow Aayla and did a body swap onto a Triad Otaku. It does alot to address the weaknesses of the Buck - in that the head no longer looks bobbleheaded, the chest is better proportioned, the stomach area is perfect, the arm articulation is muted and the legs are more realistic in the tight clothing. The Otaku is able to be painted so that shouldn't be the issue it might be with other body types. Assuming I can match the colour.
the downsides ? The pants are EXTREMELY tight and this somewhat limits movement, and I couldn't get the boots on at all. I'm thinking I'll turn the boots into bootfeet by hacking the Otaku connectors and filling the bottom with magic clay to harden them up. This should also improve ankle articulation. Failing that Triad do make some biker boots in black that are reasonably similar - all that would be required would be to add the strap around the ankle and dye them brown. Ankle articulation would definitely be improved. the hands from the buck are way too small, and the hands for the Otaku can't hold the saber properly. Will definitely need to do something about that.
The other major issue is that due to the bustyness of the Otaku, the top no longer fits. Given its so inaccurate I'd be interested in getting someone to make a new one (I can't sew AT ALL).
The size of the saber handle also is annoying, but I plan on sending an Otaku to hurricane to see if he can do a saber mod on that body, and if so get him to make a replacement hilt on his microlathe like he did for Jedi Luke.
Sorry for the lack of pics but I am without a camera.... will try address that on the weekend.
