Script to Batch adding a layered template to multiple layered psds?

Question

I have several hundred numerically named layered psds that I need to add a layered psd template on top of.  Both are the same size and will line up if I could just somehow automate the process.
This seems like something there should be an existing solution for, but I'm having an awful time trying to figure it out and I haven't found a script.  I'm hoping a script already exists and I just haven't stumbled into the right keywords to find it.
Is there some way to set up an action to import the layered psd? Perhaps split up the template layers and import images into each and recreate the layered psd?
I'm running CS5.

This might help (you need to change the filpath to the correct one, naturally).
