If it weren't so dangerous, I'd suggest a "hyperweight" that overrides prefix length. Hear bogons from route server, set hyperweight high enough to override longer prefixes, and set the next hop to null interface. Things like this return us to separation of routing and forwarding: Should BGP munching and fancy route-fu be performed on a flexible, customizable *ix box, then fed to the actual forwarding machines?
