Just be careful doing that, though... depending on the design of the tabs holding the keycap to the button, you can break the tabs taking the keycap off so that you can't put the key back on. One of my keyboards has the 5 key from the number pad where the J key is as a result of this. (I was switching the keycaps so I could learn the dvorak layout. The keyboard had sculpted keycaps, so it was all for naught. )
