I'd start with a fresh blade in the scalpel, cut each of the legs at the device body. Then remove the legs from the pcb with small soldering iron. (Sounds bad but I've never broken a pad doing this - use the tip of a rounded blade, and slice vertically downwards)

No disrespect but I personally I think this is just too risky. The levering action as the leg parts company with the chip puts a lifting force on the pad. I used to remove small-outlne packs with 0.05" leads this way but I think I was getting away with it because the wider tracks typically had greater adhesion. As soon as I started doing it on packages with 0.5mm spaced leads I started ruining PCB's so switched to hot air removal.
