I've never tried this but this makes a lot of sense in my mind's eye. I'll try this next time I have such an issue.
-------
TQFP seems nice because I can sloppily shove tons of solder down, and then just wick up all the excess solder with solder wick. In fact, I purposefully over-solder all the TQFP joints for this practice. (Too much solder during reflow, and then just a quick cleanup step with a soldering iron later).
