Thinking out loud here, but is the weak point here is the fact that most users initially think that the laminate stocks are as strong as plywood? And then get a nasty shock when a modest tap snaps it at the wrist?
The bad news is that to look really pretty, the laminates are laid up with the grain running in the same direction, rather than each layer being at 90 degrees to its neighbours.
I've seen stocks made out of ply. They look shit. You don't want to put your hand anywhere near a thin bit of any layer, as you expect to get a palm full of splinters.
The laminate manufacturer possibly could do something about it, but it would need the rifle manufacturers, or the stock makers, to insist (and possibly pay a little extra for) on making the blanks stronger.
I'm thinking that they could lay the central layers down as a 90 degree ply, and then the outer layers inline for aesthetics. Just needs the stock maker to say how many layers are in the strong central band, and how many decorative layers each side after.
