This is a very simple effect that does not require back-of-the-hands stealth or any other manipulation skills. I haven't performed this in front of an audience but I believe that it is the kind of effect that may have good audience impact.

But, as with some effects, it takes "attitude" to perform it. Often, things that a magician thinks to be too obvious are a surprise when performed, eliciting positive audience response. This could very well be such an effect.
