Is the ultimate destination of -all- the traffic originating from  
Site B (or northbound of there) Site A, from your perspective?  Is  
there any BGP involved, or is Site A participating in your IGP, or  
just taking default from you?  What about Site C, same questions?   
Also, how are the T1s loadbalanced, and are they loadbalanced on both  
the PE and CPE sides?

When you say you want the inbound/outbound traffic to be symmetrical  
in nature, is this because you require that symmetry because of a  
stateful firewall or some other kind of policy-enforcement device  
which needs to see both sides of each conversation?
