Ranked ARAM Idea

I know people will down-vote this post but, I'm not calling for Ranked ARAM--this is just an idea. Don't get me wrong, I would love it if Riot implemented something like this but, I know its more of a dream than reality. even so, here's my idea:

I propose that Riot implement an ARAM roster system so players can create a customized pool of 40 champs to use in Ranked ARAM matches.

This is how I envision the system:

1. Player must have a minimum of 40 champions (can use free champs)
2. Player creates a roster of 40 champs that he/she will use in Ranked ARAM games
3. 10 bans (5 per team)
4. Random assignment of champs (no two players can have the same champ--same as now)
5. Players on the same team may trade champs during the champ select as long as the champ to be traded is on both players' champion rosters
6. No re-rolls

An ARAM roster system for ranked play would allow most players to participate (40 champs isn't that many) and it would keep people with ARAM only accounts from dominating ranked ARAM play. It would also allow for a TON of strategy when queuing with a team.

That's my two cents on Ranked ARAM--may the down-votes begin!
