A good idea. I learned some years ago from an electrician about why they made polarized plugs the way they did. On a polarized receptacle, the neutral conductor should always be the larger blade or slot. According to my electrician, the NEC reasoned it should be this way because toddlers are prone to sticking things in these slots (hair pins, nails, paper clips, etc.). The toddlers would usually try to stick something in the BIGGER slot in their research, so they decided to make this the neutral conductor, minimizing the shock risk. This story helps me to remember which is the neutral on a cord or an outlet.
Of course, nowadays it doesn't matter, as they are requiring childproof outlets.
