Champion Free Week Idea

I have a so-so idea about how to select free week champions. My idea was to have a poll board where people can vote for a champion they would like to see in free week. But, there can only be a selection from 20 champions per week and the 2 champions from the ADC, Support, Mid, Top, and Jungle brackets will be selected for free week. So, 4 champions from each bracket will be in the poll board each week, and the ones that actually get into free week will get taken off the next week so every champion (Yorick excluded till rito does something about him) has a chance to be apart of the poll.
