I just did an extensive google search for any type of modification that remotely resembles your idea. I can not find any of the like. So you will be one of the first if you go through with it.
I would imagine this is a job for a cosmetic surgeon, and would come with a hefty price tag as well. Perhaps you should make a few calls and set up a consultation with a respected local plastic surgeon.
Let us know what info you find out. This is incredibly interesting.
