I've done it in the past, and a few more time during an emergency or when I needed a funny size for burn testing. Yes, you do pretty much what you described, but be careful not to stick the wick too far down into the clip or it won't sit nicely in the container. Also, when you pinch the metal together (I use a small needle nose pliers for this) don't pince TOO hard or you'll bend the base of the tab and again it won't sit nicely.
