Absolutely flawless, and really clever solution. Thank you for this.
Edit: Adding an improvement to this - since the Levels node averages pixels that are brighter than 1.0 too, and throws their values in the mix, bright spots can drastically dim the scene even if it's not needed.
By adding a new input node for an image, and plugging it into the Scale node's input within the group, you can input a normalized version of your render while leaving the original image plugged into the RGB curves node at the end, this way the image that controls the exposure won't contain pixels brighter than 1.0, but you can retain your highlights.
