drywall stop bead
If you want to try it, it will cut easily enough with a good pair of snips or even some fairly heavy duty scissors. For a couple of bucks for a "test" piece, it's easy enough to find out. I have cut down metal bead before for a custom fit and it WILL work. I guess I just don't see the need in the reveal, but I'm not really a decorator type. My wife says all of my taste is in my mouth....
