I have, but it took HOURS AND HOURS AND HOURS!!
Also, there really is a risk of damaging the finer traces whilst doing the desoldering work - whilst I was nervous about damaging my own board, I really wouldn't want to damage someone else's.
Any advice I can give is yours though.

Good luck!
Also - be VERY gentle when moving the SMD components - the solder pads tear very easily.
