Trial by combat and bans for rules violations.

Not sure if this is a good idea or not but I have a dream.
Players are being banned or warned left and right (at least it feels that way). There doesn't seem to be any information on why or even much in the way of an appeals process out there.
What if a banned player could elect to undergo trial by combat? The banned player squares off against a champion selected by the moderators in a number of games. If the banned player wins the ban is removed. If the champion wins the ban is doubled.
Thoughts?
