Ugh, microsurgery with a backhoe.  I don't think I would try this.  Just
how are you going to fit the chip in the socket after you torch it off? 
If it is a push in socket, good luck getting it in.  If it is a ZIF
socket, you will probably make the socket unusable by the original chip. 
Those sockets have quite precise tolerances.  The other obvious question
from one who has never seen inside an ss5 is "they soldered a pga chip
on??" usually soldered processors are the type with flat horizontal pads,
that won't fit in a socket.

I'm not saying don't try it, just make sure all the involved pieces are
disposable without loss of service or severe emotional damage.
