This is easily explained away. Rukia lost 'most' of her powers to Ichigo, not all. She was still a Shinigami capable of kido and was still spiritual aware, yet possessed little spiritual power. The gigai she was in was specifically made by Urahara to further take whatever little spiritual power she still possessed and diminish it until she was a human. It wasnt until she was removed from the Gigai that she started to slowly regain her power as was supposed to naturally happen. Ichigo as explained lost his spiritual power, all of it. He has nothing to speak of in terms of spiritual power and on top of that he he has lost his spiritual awareness. Hence he is not even what he was at the start of the series. He is as oblivious to the existence of the spiritual world as most humans are. He is even more normal human then he previously was to begin with. So no thats not the same at all as he wasn't a shinigami to begin with and there was no room for that to take place. Thus the general concept rests with Isshin and what was his deal with his past and the FGT.
