Mining pool lotto

[Mooshire]

Hello bitcointalk, wanted to gauge your interest here. What if I were to set up a lotto where instead of buying tickets, you mined? For example: for every x shares you mined, that would net you 1 ticket into the lottery. If there is interest here, I will talk to some experts here about how I could make this provably fair. Please post below with questions or concerns. Thanks for reading!
