Is this lens setup too limiting?

Thanks for the feedback.  That's a good vote of confidence that my plan is reasonable.  I don't really mind switching lenses (ie a necessity with multiple primes) as long as I can keep the number of lenses I travel with down to a minimum.

We just got back from a trip to Paris over Christmas and all I had was the 40, 85 and 135.  I was obviously missing the wide end, but otherwise this worked very well.  What I typically do is leave the hotel with either the 85 or 135 with a plan of using "just" it for the day.  Plus, my wife carries the 40mm and I can always switch out if I need to for a more normal perspective.  I'd probably follow the same plan with the 16-35.....just head out for the day with just that lens (and the 40).

Thanks again,
