I fell completely in love with this design idea when it was going around, but if we are going to keep having dead folks on our money, I'm totally in favor of dumping them all off and replacing them with other folks. Yes, even Hamilton. I'm not interested in applying the Smurfette Principle to currency. Having only one slot available and that slot getting fought over-- not interested. Let's get more than one.

(actually, I do wonder why we don't follow various other countries and have the head of state on our currency. Maybe because then we'd be redesigning them every 4-8 years?)
