I CURRENTLY HAVE AN OLD SINGLE GANG BOX WITH 3 DESPARD SWITCHES. THE TWO OUTER SWITCHES HAVE A RED AND BLACK WIRE AND THE MIDLE SWITCH HAS A BLUE WIRE ONLY. THERE IS A JUMPER WIRE FROM EACH OUTER SWITCH TO THE MIDDLE SWITCH. I WANT TO CHANGE THIS TO A 3 GANG BOX WITH 3 ROCKER SWITCHES. CAN I DO THIS...
