It would explain why Kubo didnt show current Zaraki Kenpachi in the flashback and why noone would recognize (Ichigo)Kurosaki's name. I'm assuming of course that when current Kenpachi and Isshin fought for the captain spot, Isshin faked his death so he could live in the real world uninterrupted by soul society.
You are amazing dude, I had this same idea ever since I saw Isshin get his Shinigami powers back. It would also make sense if you think about it-- Zaraki Kenpachi got his haori offa the previous 11th Captain. He's sleeveless and tattered. Isshin's Shinigami Captain haori is but a piece of cloth over his shoulder, almost it like was ripped up... it all makes sense in my honest opinion.
Also this shot out to me, reading his bio on Wikipedia:
"
During the Arrancar arc, Zaraki appears to Ichigo as his instinct and desire to win, explaining to him that they were both the type of people who lived to fight battle after battle. After Orihime is taken to Hueco Mundo, Kenpachi arrives with Byakuya Kuchiki to retrieve T?shir? Hitsugaya's group and bring them back to Soul Society. Later, in Hueco Mundo, Kenpachi comes to Ichigo's aid during his battle with the arrancar Tesla, dealing the arrancar a mortal blow with a single strike and then engaging Nnoitra Jiruga in battle. After sustaining several injuries, Kenpachi emerges victorious by using kendo, landing a massive blow to Nnoitra. Kenpachi stands over Nnoitra's corpse and thanks him for a good fight."
The bolded part just jumps at me that there's a connection between Ichigo, Isshin and Kenpachi, maybe because Isshin probably had the same mentality back then.
