EE... units without such a requirement become basic core units and that's never going to work for 'heroes'. They need a culture to be based on so maybe there's still yet one they can be assigned to. In all honesty, cultures are fairly easy to setup and define. Units, on the other hand, are tough. I'm working on a lot myself at the moment. Perhaps later we can revisit some of the ideas that are being removed but if a culture serves no purpose in the game but to be there, why have it there? I wasn't really familiar with either Leon nor Castile but if y'all feel that they are justified as cultures, sure, we can keep them or just disable them temporarily until someone decides on what a good unit to define them would be. Good luck with that sort of monster project tho.
