I guess I'm just a little slow - you've got the f.4 "trinity", are getting a second full frame body, and you want to
upgrade the lens you use the least? Why? If you absolutely have to spend another 1300-1500 Euros, fine, but
I think your planning is a little weird. Why not upgrade the 17-40 to either the 16-35is (or wait for the new wider, longer model the rumor sites tell us is due in less than a month) or the mid-range for the 24-70 f2.8? It seems to me you'd get more "bang for the buck" with either of these choices than upgrading the lens you use least.
If you have to get faster, longer lenses, consider upgrading to two beautiful primes, the 135L and/or the 200L.
You run the risk of finding out prime lenses are a bit more challenging photographically than the zooms, but they
do provide wonderful images. You might even pick just one of these and "upgrade" to the 70-200 IS f4.0 version
since lens speed hasn't seemed to be a problem with your other focal lengths.
