Currently the only BFD samples you can convert (as in not re-sample) are BFD2 as they were stored in multi channel .wav files, so any editor which can open those will be able to allow you to mix every track to your liking and export. Reaper will do it, for example.
Someone has converted the BFD3 Core Library to Kontakt, no idea how they managed to do that but I cannot post a link as the websites it appears on are questionable and it's also not exactly legal! But it does make me think there is a way to do it...
