Yeah, definitely. And at this point is not even really all that much to ask, imo -- even just providing the option of the same existing bodies but with SLIGHTLY smaller busts would do wonders, and allow for so much more variety as you say.
This is something that I have always been critical about toward seamless bodies in general -- for all their purported 'realism', they tend to stray too far into 'heavily idealized' territory in so many other ways, especially in the almost cartoonishly large bust shapes/sizes on some of their female figures [and muscles on the male figures].
Likewise, there are many body shapes out there that are considered 'beautiful' these days. Which is why it does irk me sometimes that they choose to perpetuate some very narrow and out-of-date ideas of both male and
female beauty. Of course, I understand the argument about the fact that they still need to sell these things, but in my opinion, they are underestimating their 'audience'. Or at least, the potential
of their audiences. If they started a line of less-busty ladies, for instance, they might even widen their appeal into the doll-making community, who like flatter chest figures for their fashion dolls for reasons both practical and aesthetic.
And that's just one single example -- there are many other ways they could easily branch out. Of course, these things take time, and I'm not really complaining too much, as they have at least recently put out the above buxom body, which was a really good step in that direction.
