Aside from the first step - I would have hand-soldered a couple of
corner pins, that is the way I would do it.

Solder wick works great. I sometimes use a flux pen to flux up the
component leads to aid the process of removing the bridges. It should
also work on its own if you had good solder wick. (They have some milld
flux in I think).
