Just releasing something i have found out while trying to add patches (login screens,re textured battle grounds and more) to pandashan wow private server but this also works with all releases of wow up to current 5.4. If you don't want to use a modified wow.exe you can always put patches in your wowfolder/data/cache. Rename your patch to patch-base-16016 or any one of the patch numbers in that cache folder up to patch-base-17345 and replace it with the same one in wowfolder/data/cache. If your patch didn't work try renaming it to another one of the patch-base-xxxxx in that cache folder.
