This is probably a dumb question, but I was wondering if this setup I have in mind is possible and if it is ,.. is there a reason to do so.   
  
One guitar into the pod hd500x 2 separate signal chains, 1 panned right the other panned left. 
  
 Left output into channel a of the simul class right out into channel b of the simul class.   
  
Channel a out from the simul class to a 1x12 v30 cab  
  
channel b out from the simul class to a 2nd 1x12 v30 cab.
