Is a head width reduction possible? (photo)

Hi, I've wanted a narrow head for a long time. I could live without a narrow head, I don't think it's vital. But if there is a way to slim it down I wouldn't say no. I heard there is an op called Temporal Reductions. What would be possible? Would something like that be possible as can be seen in the pictures? I can be seen in the pictures. haha. I narrowed my head with a photo editor just to see what I would look like. Thanks, greetings sebastiano
