   I'm trying to get my head around the math.  If you have six and combine   
   two more on one of the six, doesn't that make 8?

   Not sure what you're planning, but if there is ANY wire smaller than   
   #12 anywhere in the system before or after your 20A breaker, you've got   
   a problem.

   Acting on answers  you get on the web is risky.   
   Some people here know exactly what they're talking about...some don't.   
   It's impossible to tell which is which.   
      
   There are two people who care.   
   1)The local building inspector who'll sign off on the inspections that   
   come with the permit.  Call 'em up.   
   2)Your insurance carrier.  They'll probably not care if the building   
   inspector is happy.   
   You are gonna get a permit and have the work inspected??right???   
      
   Around here, an electrical permit costs way more than a lifetime supply   
   of batteries for bedroom emergency flashlights.   
      
   You don't say where you are, or exactly what's happening, but I expect   
   your solution will be "frowned upon" by the inspector.  Call 'em up and ask.   
      
   As usual, the time to think about 9 circuits is BEFORE you have six   
   installed.
