    Yes it is possible however if you can just swap one of the chips over that works better. I used a heatgun to get the chips off to fix quite a few of mine.

    Same way you took it off, line it up perfectly with all pins in correct position don't apply any pressure as you will spread out and end up shorting the heat pad solder.

    Think I heated them up to around 230 degrees, I used a laser thermometer

    Edit: I protected the back of the board by covering it with tin foil pushed down to the pcb.
