Suggestion: Raw Healing iLvL %

Would it be possible to get a ranking similar to iLvl % that ranks healers based on raw healing within their class, spec, and gear level?

This would be helpful in analyzing effectiveness of recruits whom are under geared compared to the rest of the healing team. It would also help identify issues where a player is outputting as much healing as other players their ilvl and spec but where their overhealing is significantly worse.
