I don't find the Bounty Hunter or the Fighter Dervish oddball.
As for the Archaeologist Rogue, while not appropriate for any campaign that I would run, I don't consider the archaeologist to be oddball either. It would be appropriate for some worlds. There were antiquarians in both 11th century China whom analyzed alleged artifacts. There were also antiquarians in ancient Rome (whom were more like historians than archaeologists). Even before then, there were some rulers that were interested in relics Therefore, it is not unreasonable that someone like them could not go adventuring in search for artifacts in a campaign for their own study or to bring back artifacts if appropriate for a culture. Then there is there is the rise of Antiquarians during the Renaissance, I could definitely see an archaeologist Rogue as an adventuring antiquarian type during this time.
Finally, I don't think a Nymph blood sorcerer is odball either since several mythological Greek charcters had a parent whom was a nymph. In some tales, the sorceress, Circe was nymph.
