Judgements about money aside, you are in the middle of riots and mosh pits with multi-thousand dollar cameras that are large, easily damaged, and easily stolen? Sorry, that's just nuts.
You are shooting editorials for print, you don't need the resolution or color accuracy for wall size art gallery prints. If it were me, I'd be looking at something like a used Rebel T3/T3i (or if you don't have to have Canon, a Pentax K-30 which takes incredible pictures and can be had for just under $400 *new* on sale) with a cheap but capable do-it-all lens such as the Sigma 18-250.
If you are willing to step away from DSLR for your assignments, take a look at the Sony A6000 and see if it works for you. The DxO scores are very impressive, bettering a lot of the mid-range DSLRs out there.
