I have the 24-70 and 70-200 you are considering and if you can afford them then absolutely get them. I agree with Neuro that the 2x III TC is the best way to go instead of the 100-400 as their are daily rumours that it will be replaced soon. I have the 16-35 and have and continue to enjoy it and bought it in preference to the 17-40 for the reasons others have explained. Knowing your wide range of interests a TSE may help better than the 16-35 or 17-40. I recently travelled to China with the whole kit and I can tell you it is heavy and whilst if I left anything back I may worry that I hadn't the right lens at the right time, I will on my next trip.
