Will an 'alias' help you?   like this

server> ruby a.rb
1
3
1
server> cat a.rb 
class A
  attr :t
  def initialize
    @t = 1
  end
end
a = A.new
puts a.t   # => 1

# Not extending... redefining here....
class A
  attr :x
  alias old_initialize initialize 
  def initialize
    old_initialize
    @x = 3
  end
end
a = A.new
puts a.x   # => 3
puts a.t   # => 1
server>
