What you are describing could be a challenge to implement for the very reason you state, BGP is doing what it is supposed to do when it advertises its best path.
A different, and potentially more useful approach that gives visibility into each router, is to use a distributed LG approach. Hurricane Electric has a very nice IPv4/IPv6 interface that runs on their Brocade routers around the world. They would probably even be willing to share code. You could extend the functionality further to implement the per-peer options. http://lg.he.net/ The routing software features between the XMR and CER are the same, since each software image is compiled from a common source tree. The only different in the platforms are hardware capacities and hardware features.
