should fit,might be a bit tight (will only just fit the 70-200 length ways), I use a couple of Nova 200AW for all my flash gear. The shoulder straps are comfortable and heaps of space
I would say go with the nova 200 then you can leave the body on the 70-200 in the bag and partition for the other accessories. I can put that gear in a 200AW if you like tonight and post a pic for you to see
