just to say, you can take the body part specific morphs in your custom morph to 0.  if something just affects the chest and it's already in the custom morph, you don't need the original anymore. 

i will say this.  i don't think that if you don't solve this problem that any merchant will happen to make this specific morph, unfortunately.  especially if NBS isn't doing it for you.  you might try starting with noggin's Molly at DAZ?  i think she's much older than you're wanting, but maybe you can use her morph as an addition to your others?  sorry, just trying to come up with a good answer...
