Boxer views support multiple inheritance via the :extends option, which simply merges each view into the previous, in order:

Boxer.box(:user) do |box, user|
  box.view(:base) { {:name => user.name} }
  box.view(:full, :extends => :base) { {:email => user.email} }
  box.view(:search, :extends => :base) do
    {:last_seen_at => user.last_seen_at.utc.iso8601}
  end
  box.view(:full_with_time, :extends => [:full, :search]) do
    {:current_time => Time.now.utc.iso8601}
  end
end

Which would give you:

>> Boxer.ship(:user, User.first, :view => :full_with_time)
=> {:name => "Bob Jones",
    :email => "b@a.com",
    :last_seen_at => "2011-10-18T19:00:52Z",
    :current_time => "2011-10-18T19:02:34Z"}
