I'd absolutely love more bodytypes!! For all types of characters. So heavier but with evident muscle definition, or heavier but softer and that also goes for leaner/thinner builds for all genders than are currently available. We probably don't get height options aside from the very specific per race ones but that would be a major boon as well and really add to the individualization of your hero and let them stand about and be connected to the player.
In my case I would have loved to have a more lean but toned option for my males as it fits my preference for them much more. I know some players find them too thin already, but I'm the opposite. I actually was a little disappointed that my elves looked a bit too thick for my taste.
Please note that this post is not about whether Larian will, or can, or should (have) and it isn't about potential technical difficulties & resources etc. It's voicing a wish/want from a personal perspective as a particular player, that's all. It's still valuable for Larian to know, if not for this project, then maybe the next.
