In theory a skilled technician could use a heat gun to desolder the chip

removable.

Safest way for a non-technician to remove a chip that is already toast
anyway is to cut
through all of the leads. Remove the IC package, then use a soldering iron
and tweezers
to remove the remaining leads being careful not to leave any solder bridges
between the
pads. (Hot air rework stations are an acquired skill so that you don't lift
any traces or
pads.) BTW, if you do accidentally get a solder bridge, do not power up the
board until
you manage to get rid of it...solder wick works well for that.

It might be easier written than done, cutting though the leads without
gouging something or pulling up pads and traces. It would seem that given
the spec sheet, only a few of the leads would need pulled up from the
pads, presumably the power and one or more bus lines, then the chip could
stay on the board.
