As noted in the first link, the void space will be the deciding factor on the lead weights. Likely ends up weighing more than the sand but you can't use the wheel weights to spread on the ice your car is stuck on for traction, can you?

i'd rather do what the OP was talking about and melt it all down into flat slabs to lay back there. extra points for putting in holes and bolting it to the car.
