Well, I see no reason for samurai to have no talent in ninjutsu. Of course, it depends on the individual qualities of the particular person, but since Guy/Lee are still exceptions amongst regular shinobi, I don't think that among the samurai would be more people like them. It's just about samurai never being taught ninjutsu due to their culture (aside from the chakra flow on swords), not due to them lacking any ninjutsu talent.
