At first glance using Hermes sounds very messy to me in that you must  
either using inter-board cabling to ensure the multiple receivers are  
coherent or try to find Atlas bus lines that will do the job for inter- 
board comm.  While I suppose it could work I would opt for a  
completely separate board from Hermes, I think.  I'm not saying I  
wouldn't want to play if Hermes with an add-on board was selected but  
it wouldn't be my first choice since Hermes really wasn't designed for  
multiple ADCs and we'd start right off patching up things which often  
leads to a messy/unreliable final configuration.
