They should be interchangeable, but for some reason they are not, so the HL do not recognize, lets say, a Crane Variant Samurai that took Weapon Focus (Katana) as having the Weapon Focus Feat requirement for the Iaijutsu Master PrC, both of the same source.

I can add to the pre-req so that Weapon Focus (Katana) counts as Weapon Focus (Bastard Sword), however I think this will need to be done for every instance individually so you'll have to let me know if I've missed anything.
