It's hard to figure out whether this is supposed to be a genuine request or trolling in this day and age...

...all things considered, I remember NWN1 having a "default" and a "heavy" model for every race and both sexes. "Heavy" fell more into a "burly but also rotund" category there, though. Still, with all the animation work required and the already abundant clipping with the existing models I highly doubt that this is in any way a priority to implement. I am not sure how the armor being fitted to models is done by Larian, but given how there were several cases of wardrobe malfunctions for certain suits with non-standard body types I am kinda worried that they are all adjusted by hand instead of having modifiers for the models.

Myself, I'd rather see slimmer halflings and slightly portlier gnomes. Halfling women have an... anime-like look to them proportions-wise, for the lack of a better term. Most female models could use a bit of adjustment. Being able to get rid of abs and body hair (everyone except for elves and gnomes has it) on men would be a welcome touch, and not even that difficult - heck, modders have already done both to my knowledge, since it's just texturework/layering that doesn't need any mesh alterations.
