One of the really clever little aspects of the review tab is that it shows the number of posts in the queue, giving people some psychological incentive to work on it in order to make it reach zero. With the suggested edit queue's single-digit count, it seems to be a quite effective trick.
The problem is the two other counters. The closed votes queue, seems to be stuck at its current 58-59k mark, and many of the close votes regard year-old posts which quite frankly would better be left to rest in peace.
Could it not be tweaked or split up so "hot" close votes for new(ish) questions could be brought to a more manageable size?
Then people who are interested could have a 50k-sized queue of questions from 2009 (which no one has touched since) and mull over the question if they should be closed or not.
The low-quality posts are slightly different, as they are slowly, but steadily being worked through, even if it means that the community has to mull over thousands of long-forgotten posts.
Also in this case the queue could be split, so year-old forgettable answers to forgettable questions can just be, well, forgotten in a queue all of their own - so people don't have to wade through them, one by one in search of some gem to rescue.
This would make it realistic for users to help bring relevant revision queue counts to zero, and that gives a warm and fuzzy feeling.
