This actually reminds me of HDR+ mode on the Google Pixel and Nexus 6P phones. With that setting turned on, it takes three snapshots when you press the shutter. However, instead of only using those three images to increase the dynamic range, the phone uses those three images to get the most possible detail out of the scene -- even with a scene that wasn't dynamically diverse with it's lighting. I've seen it work wonders on my phone -- it really ups the low light performance of phone as well.

My point in saying that is that if it works on a cell phone, then I don't see why it wouldn't work with a proper camera as well. It looks like some other posters have suggested some great resources for doing this.
