That is not possible. You need atleast to guarantee that the node is
inserted into a Document originating from the same DOMImplementation.

Furthermore, your instances are of the wrong class: "good" nodes are
instances of subclasses of Node.

I believe what you want to do is not possible with standard DOM
API. So you need to revert to implementation-specific extensions. For
4DOM, you can use _4dom_setOwnerElement.
