Giving one object the shapekeys of another object.

Okay, so I have the Generi modeling rig that’s out for Maya, and have imported it into Blender 2.4 alpha. It has the head, and a bunch of other heads which Maya uses as morph targets for lip sync. What I’m wanting to do is to create a shapekey for each of these head, then import it into the main head object as shapekeys. My question is, how do you give one object the shapekeys of another object? More specifically, how would you give one object the shapekeys of more than one object, as in the example above?

may be feasible using a script, I’m not sure of the current state of the API regarding the Shape key access, as it’s fairly new. Imho, if they all contain the same number of vertices. it’s feasibles.
