I also have the I have the 17-40, 24-70 and 24-105.  I can do some test shots if you can wait a little.  However, I think they all have enough distortion that you would probably want to avoid having people's faces on the edges anyway.  ideally, I would not go under 35mm for group shots.., but I understand that this is not always avoidable.

Yeah..., we just have to work with it's limitation, and take advantage of what it offers, and avoid what you don't like seeing on your pictures..
