Creating an Overwatch system like the one in CS:GO?

I wasn't exactly sure which discussion to post this in, so I apologize in advance if I'm in the wrong place and/or this is already been posted.

Anyways, everyone has had their fair share of players who AFK, intentionally feed, troll, etc., and I was wondering if it would be possible to introduce an overwatch system where players can spectate games from their ELO (targeting the players that had been reported for something) and the player can decide whether or not that player deserves to have their account suspended for X amount of hours/ days, or have their ranked queue temporarily disabled until they play X amount of normal games without being reported.

OR

Higher tiered, and trusted players who have NOT been reported or banned can use the system to watch a random game where a player had been reported, and then the spectator decides whether or not they should receive a punishment for their bad behavior.

I would also like to apologize if this had been mentioned previously or if it's a little hard to understand.

Any thoughts?
