   Well I think that Boeing will want to fix the issues with the 3 CBC   
   version, before strapping 7 of them together :) Or at least I hope   
   they do...   
      
   Actually there's been a large number of discussions on this very   
   subject (mainly) over the last few years, over on sci.space.policy,   
   take a hunt thru google for Delta IV Super (or Mega) Heavy, amongst   
   other subjects.   
      
      
   The 7 CBC models would require a new pad according to Boeing, so they   
   are definatley some years away, and probably won't happen unless a   
   Delta IV Heavy derevitive gets picked for the Exploration Programme.
