You completely misunderstand the role of BGP.

See my draft stating:

   However, to enable source address filtering to discard packets with
   source addresses not belonging to an ISP, it is useful to enable a
   host, not some intelligent intermediate router, select a source
   address compatible with an outgoing ISP.  For that purpose, intra
   domain routing protocols or something like that should maintain
   routing table entries with not only preference values of an external
   routes, but also proper prefixes to be selected for source addresses,
   if the entries are chosen by a host.

It should be noted that it is already doable with the current OSPF spec.
