Maybe, but I don't see the point. Speaking with your hands is weird no matter what you are doing. Learning ASL signs instead of something else is that much harder, and ASL is a lot richer than either.

Of course I can't claim any ability in ASL. When taking the baby sign language classes my teacher was very insistent that to the baby what sign you use doesn't matter, but we should use ASL signs because learning any other sign isn't any easier, and this way we have a few dozen signs that are actually useful after the baby grows up. Which is the point: if you learn some signs of ASL you can communicate better than pointing. When you learn something else your are just pointing and hoping you are understood.
