Clearly, you do not have enough kit.
May I suggest, a 5DIII, 5DII (or 7D), 300/4, 1.4x, 100USM macro, 50/1.4, 35/1.4, 24-105/4, 16-35/2.8, 28/1.8, 28/2.8 and 20/2.8, all in two Domke "F1x" bags (little bit bigger). Top that off with a Majestic double leg tripod and a Leica Tiltall tripod for backup. Then pack a pair of White Lightning 600 Ultras, three old 283's, three Chimera banks and a three Matthews Beefy Baby stands.
Then after packing it all "just so", find room for an M4P and 35 Summicron, and an M6TTL with a 50 Summicron (or alternately 28 Summicron).
Be prepared for a decent amount of prolonged wait time at airports, try to avoid Reagen National if at all possible.
