5 Man team aram, re rolling the perfect team.

So a buddy and I, figured out that with 4 re-rolls total, and switching champs back and forth, aram doesnt have to be so random. has anyone tried to reroll the perfect team with a group of 5, ie keep switching and rerolling till you get the team comp you want?

Ps: I feel if riot made it where you always have 2 rerolls, aram could possibly be more competitive. With this it would be fun to see both teams selections ie like draft, but you can scrap a champ or 2 that looks like it would be countered, thus counter wars begin in a whole new light.

thoughts? comments? or is this a bad idea?
