Model origin vs scene positioning shadow-cast problem

[db11]

I have a model of a house (with terrain) where the model origin is at the main floor bottom corner. I have created over 60 scenes to map an animation path through the model.

Because it is a sloping lot, I have a ground plane tree shadow problem — the trees cast their shadow at 0 on the z axis and not on the slope below the ground plane... leaving floating shadows.

So I want to effectively move the model origin one floor down (~9') to the basement bottom corner. Since I can't move the actual origin, I can only move all the objects (house, terrain, trees etc) up 9' to fix the shadow casting problem.

However if I do that I screw up my entire animation path since the scene camera positions are calculated from the origin. Anybody know of a plugin or a couple of lines of Ruby code that would batch-fix all the scene positions by 9' on the z-axis?

Or is there an easier way to approach this?

You can set the shadow settings (in all scenes) such that it does not display cast shadows on the ground plane. In the Shadows window (expanded pane). Then you probably would want a script that can do that.
