yes it works, and is more natural, but is a pain to do and will slow down the growth of the plants (since they aren't getting 18 hours of light to grow in anymore, just 16,15,14,etc.), thats why most people just go from 18/6 to 12/12.
And, the words of few do not outweigh the words of many. If your plants die switching to 12/12 they were gonna die anyways.
