The trick I usually use if I need to do something similar to that is
to create a constructor for the subclass that takes the parent class
as its only parameter. Then you just do

$obj = new Blah();
$obj = new EnhancedBlah($obj);

Same type of effect and you can still use the $obj anywhere you have
before because its a subclass now.
