I was keeping up with the topic too Paul, thanks for sharing the finished figure.
It's a better head using the Jinx figure I think... Much more true to the MOTS box cover. I'm still not sold on the torso though really, only because I think the Star Wars line lends itself better to the overall "look".
I think a torso like Droid Factory Padme's perhaps would've worked better maybe? I wasn't a big fan of the Joe torso idea ever... Joes are only good for accessories and heads I've found, though you did blend the lower leg with the Han Cantina upper legs quite well.
As a secondary choice, and I think you used this on your previous attempt, I think the Aura Sing body's superior to grafting a Joe torso as well.
I think the smaller Jinx head would've set better on a smaller SW figure torso then too, and it could've been grafted to the Han legs to make a curvy woman's figure.
The accuracy of the figure seems pretty good though overall... The paintjob seems pretty good too, keeping true to the character on the box, though the skin seems pale. Easily could be the camera flash though.
My only other suggestion beyond the torso was perhaps trying to use the Luke Ceremonial jacket over Hoth Leia's... Leia's is a bit small, kind of untrue to the look on the box, but the Luke's is the exact style. I don't know if the "exagerrated" chest on the Luke figure (and subsequently his coat) would have benefited fitting her, ummm, "attributes", haha.

Good work Paul! She needs a Dark Kyle to fight now though!
I don't see many MOTS Mara's ever surface with her purple saber. To me, the purple saber was her trademark more than the Luke saber really... It gave her some distinction.
