ARAM Ranked System

ARAM Ranked would work well in theory but aram isnt a balanced game and doesn't need to get balanced since its a novelty mode. The randomness pulls away from the current ranked system since you sometimes lose at champ select so what if that happens in a promo multiple times, doens't display skill rather bad luck. When you get to higher elos if you arent using an aram only account then you will be at a disadvantage as well.

There are sites that calculate your aram mmr which will then give you an idea of where youre at. As for an official ranking system. Not plausible for Riot

And give extra rerolls in that mode for better team comps!

There's various aspects that would need to be considered/discussed for Ranked ARAM (e.g. placements/promos, bans, champion availability, rerolls), but overall it'd be great to have another avenue to demonstrate skill.

Yeah no its already bad as it is with ppl rerolling just tanks and poke only champs.
