That and you mentioned he was young. Say if he was just slightly older than 'Ranko' is in the present, one of the reasons he could not summon the light hawk wings, its possible that they would not have recognized him at all. There are a fair variety of people in the Kurumitsu family (Genma is lazy, Soun is really tranquil, etc etc)
However its a nice touch. Remember even getting to ten wings took RANMA ten thousand years. I would assume even knowing how to get there, the power necessary means that even summoning one is far beyond Ranko is present day Tokyo. She is powerful after her training but not Lighthawk Wings powerful.
Hmm, you have to explain why Arashi is not considered one of the 'lost ones' the 'only Kurumitsu's to have died.' Is his body in perfect health waiting for his soul, or is there another reason. Will Enma recognize Naruto?
