How about this? Use multiple anchors.

database: &default
  server: &server
    ip: 192.168.1.5
    port: 2000
  db_name: test
  user: &user
    name: root
    password: root

foo_database:
  <<: *default
  server:
    << : *server
    port: 2001
  db_name: foo
  user:
    << : *user
    password: foo_root

It's just a little extra work, and slightly harder to read than if what you wanted were built into YAML as you suggested (I thought it would work that way too). But overall not bad.
