That wouldn't work. At all.
Just think about it. Now the TO has to buy a new set of dice for every single player, because good luck reclaiming a door prize which would effectively be what this is. And since everyone has to have a decent number of dice for those armies that roll a lot of dice, you'd probably need to go with one of those 36 dice packs. That's like $10 a person, at least, adding up to several hundred dollars for even a small tournament.
Then look at it from the player standpoint. I went to about 10 tournaments this year (Sacramento's flgs has a tournament circuit, and I went to several other various tournaments). If I was issued a new pack of dice every time, I'd have a few hundred extra dice sitting around, but because I get issued new dice and can't use my own dice, I have literally a box of dice that have been used precisely one day, then tossed in a box to be forgotten and replaced.
It's absurd, and it frankly addresses a nonexistent problem. I've seen dice-related cheating precisely once in all the tournaments I've been to, and that was as much about the player fastrolling and lying about results as it was about the dice themselves, and the dice weren't loaded or anything, just a color that was difficult to read from across the table.
