Loading swf w/ dynamic transitions?

The effect I am wanting to do is this:

As one external swf is leaving the stage, say sliding off stage left to right ...

I want the called for swf to connect itself to the left edge of the exiting movie
and slide(ease) into the stage just behind/connected to the leaving swf.

So could this be adapted on to the transitions tutorial to make the dynamic loaded swf behave in this way?

Here is an example of what I am wanting to do:
