That thing is all kinds of ridiculous enough already though to be fair.
To answer your actual question though, yes I believe that each "unsaved wound" from that as a result of the D-Table would inflict D3 wounds instead of the one. As such, the 2-5 results would be (D3)D3 wounds, and the 6 being (
D6+6)D3 wounds.
Mildly ludicrous
