Implementing your Top 5 Champion K/D Ratios box in Champ Select?

I thought/think it would be pretty awesome to have 5 of your best champs with the highest K/D ratio so far in that game mode... Any suggestions?

For example,

88 Kills - 77 Deaths 92 Kills - 49 Deaths 126 Kills - 93 Deaths 194 Kills - 102 Deaths 224 Kills - 123 Deaths
