Ok, you made some good points. However, there is one or two flaws here. Isshin was most likely residing in a gigai (like Rukia). He did this so long without Shinigami powers that he "became" human for a intents and purposes. Also, they are sisters, not twins (unrelated anyway). I admit, I believe the ghost seeing part had to be passed down, but not the Soul Reaper powers. The Hogyokū would only work within range, and it was almost never in range, except when Rukia was at Ichigo's house, which I will admit happened a lot.
