No, I see what Fury is saying here. It's an interesting approach.
EDIT: Actually, scratch that, I don't. How exactly would armor.tbl matter if the beam is piercing the shield anyway?
Furthermore, I took a look at the code. The beam does all the unnecessary model and collision checks, including checking the shield quadrant that is hit. But then it sets the quadrant to -1, causing no shield quadrant to receive any damage and the full damage to be propagated to the hull.
More elaboration is necessary, methinks.
EDIT2: Also, if this is an official Blue Planet request, it should be on the HPC board.
