A very cool list - I wish I would have seen it when I was there. I did not realize you could break unit coherency when removing models as long as you don't move them again. I had one opponent try to do this against me, but he was attempting to break his coherency with his pile-in move which per the rules you can't use a move to break coherency.
A very odd looking "unit" i'm sure once your conga gets removed, but well played! I myself played 15 skyfires/Kairos/LoC and needed a double turn to even feel like I had a chance with my Khorne army. So tough, but glad to hear you gave him a run for his money.
