Load swf to replace entire stage

Hey,

In old AS-days we could load a swf at level0 an thus replace the entire first swf.
Now i am trying to do the same thing with AS3 but i can only seem to load it and add it as a child.

What i want to do is to have a empty.swf that loads content.swf and that empty.swf will be completely replaced, not the parent.

Is this still possible?

Let me know if i need to clearifie anything
