Forrest,
You could try running a "blob" of solder down both sides of pins. If
you get enough solder in place then the thermal inertia is enough to
keep it molten while you pull the part (using something that will grip
it at the ends).. But you do need a bit of space each side and the
part is likely to be damaged and you can have a bit of a clean-up job
to do afterwards.

And it can pull  the PTH barrels out of the board if a pin sticks!!!
