You may be able to save yourself a little time using EMACS (another advantage of ASCII file formats).
If you are changing *ALL* of the bf_SOT23 footprints then replace the string bf_SOT23 with a string that is not a legimate footprint name. Run gsch2pcb and the original bf_SOT23 footprints will be removed and the new ones will be in the .new file. You will still have to manually place the parts and cleanup copper but refdes and value will be correct. NB: make a backup copy prior to editing!
