Bitcoin Kitty Lottery

Hello! i was just sitting here right now , seeing how people do so much Gambling/ Investment / faucets to earn some btc.
I just got hit by an Idea -
Suppose, 100 people send 0.001 btc to an address that will make it 0.1 btc And than we use random.org to pick two Numbers and any two random people who invested 0.001 btc get 0.05 btc . It's just like gambling or more like Lottery.
But i got a problem , if someone receive's so many of small input's(Dust) ,as we all know , the output will have a larger fees, any idea to avoid that?

use exchange address as a receiving address and then send the coins to your wallet. You will get all coins in one chunk, the cost for that will be the transfer fee.
