I would think that hangers as close to the ends of pipes A and B would easily support 2'-0 of pipe and 6 elbows, if there is a concern that all the flexible couplings will allow the assembly to sag then possibly putting a trapeze hanger below the lowest point of the assembly should keep it level and not interfere with movement. Just a thought.
