if it could, many of us would beg someone to do it RIGOROUSLY and publish.

a few problems:
  o routing is not always symmetric, or i guess rarely is
  o you would have to do it from'*many* distributed locations to many
    distributed locations to see all the peering points through the potato 
    fog
  o heck, due to bgp best path propagation, unless you are on a router with
    which P is a peer, you can not really tell if C is a customer or peer 
    of P.
  o and it still would not tell you who is paying whom when it is peering
