Silvio, your profile states that you have the 24-70...I wouldn't go wider than 24mm as the distortion at the edge make people look funny. Are you finding that 24mm is not wide enough?
The 24-70 and 28-105 should be adequate, but if you are really looking for something wider, I would look at the 20-35 f/2.8 or 17-35 f/2.8 Nikkors. I think that the distortion at the extreme of the 18-35 3.5-4.5 would not be good for group portraits.
