Moisture of any kind trapped under molten lead will cause steam to form ,the trapped steam will find the quickest way out, if that means blowing the cover of molten lead off to escape, well you get the picture.
Moisture dropped onto molten lead will sizzle and evaporate quickly,it will not explode because there is no lid on the pot to cause any pressure,and the steam generated has an escape route.
I also think the tin foil plywood lined mold will smoke it may not ignite but it will generate plenty of smoke.
If you are just looking for weight, what zinc you encounter won't make any difference, but you will need some way of skimming the steel weights and clips off the melt.
May I suggest some cheap stamped steel cookie sheets from Wally World for molds they are about 1/2" deep with a nice lip and 18"X10".
