I would love age and body types as well. Plus some changeable features to the face. But except body types and maybe even for those, I'm not sure how much Larian is willing to put in considering those face presets are 3d screenings of actual living models, just slightly moderated for non human races. That's a lot of time and money spent on something that gets changed first thing by players if too many options are given. I can argue that ears, beard, hair, make up etc, stuff that doesn't change the actual face model is quite easy to put in. And I truly believe there are more presets coming. And body types won't change the face but might make it look disproportionate to the body. I. e slim face/large body.
Age though.....I guess you could just make artificial changes similar to make up like wrinkles and such. But having your skin starting to thin out and hang is a whole other question.
