Well, the sigma you can always get again in Nikon mount if you wanted, but i'm sure you knew that already.

The 24L will be length-replaced by the 14-24. How much did you ever shoot it wide-open? The 14-24 is pricey but I'd say it's worth it to replace the 24L and 17-40 in one, for 40mm you can always crop away some of those 36MP...
The Nikon 85/1.8 G is a bit better than their D, i'd guess probably about as good as the EF 85/1.8 (although in the f/1.4 area, the G craps all over the D).
How about the Sigma 150/2.8 Macro to sort-of replace the 135L? Nikon also did a 135/1.8 and 105/2.0 in years past, not sure how well it'd stand up to 36MP though...

Still, I'd be happy with that setup. (Did i mention it's my birthday tomorrow? Equipment/cash donations gratefully accepted)
