As much as I'd love this...we know they won't do it. People have been asking for more options in general just to have them largely ignored.

It's technically possible for them to create new body types via gear since they actually work more like 'skins' if that makes sense. There's a few things that already change the body shape compared to the base like the 2B leggings and the Monk AF2 chestpiece.

But base-wise, they might just excuse it by saying it might stress out the servers, just like anything they answer about more character creation options. I can tell it'll also be just a lot of busywork to redo the gear to accommodate new body shapes in general.

With the success Shadowbringers has been, I really hope they give it a needed overhaul.
