A few years ago I shot some fire dancers and looking at those shots and I did get some keepers at 1/60, f/2.8, ISO 3200. But I also remember wanting more light and throwing out a lot of shots as I tried higher ISO and slower shutter speeds. So you might consider something faster (85 f/1.2? 135 f/2?) and practice with it now. I think you have wider covered (24 f/1.4). Or maybe you feel good enough about ISO 6400/12,800 with the 1DX.
Personally, I think I'd go with f/2.8 zooms for flexibility and raise the ISO as needed. I have both the 85L and 135L, my concern with using them at events is DoF – even with individual portraits, I generally stop the 85L down into the f/1.6-2 range, with >1 person in the shot you'll often need careful posing to get faces in focus at wider than f/2.8.

I get usable results with the 1D X at ISO 12800 with DxO Prime NR.
