To point out the concepts you have brought up are largely based on what you think rather then facts (something you didn't express outright, you just said possibilities as if they could be but they are just as likely not at all possible).

1.) You are correct about how Aizen finds out about the Royal Guard 110 years ago, but we largely have no information about if any information is kept on them as it seems to be knowledge passed down through the captains. So doubtful he could have read about it anywhere if he wasn't already privy to the information which most outside of the captains dont seem to be.

2.) There is no connection that he even remotely knows of Isshin as he seems entirely unfamiliar with him even with his claim of watching Ichigo since birth. He even seemed to question that the two were even related.

3.) On top of that the outcome of what happened to the Vizards didn't concern Aizen as his test was what took place before the arrival of Urahara, he was already finished with them, having achieved his goal whatever it was and was about to kill them all. As far as what happened to Urahara a simple frame up only requiring planting of evidence and knowledge of how Soul Society works mixed with some of his illusions. Also Aizen didn't gain control of the Central 46 chambers until 100 years later when Rukia was found by Soul Society. His explanation to Shinji had entirely to do with his illusions placed on Shinji and by extension others which set the stage for them all be under his absolute hypnosis. The concepts are two separate situations.

4.) Isshin was never a remote factor in these plans so how can that be a bases for your assumption. Hikifune's promotion had no affect on the Gotei 13 except providing an opportunity for Urahara to elevate in rank. She was by and large not even an important character to make the concept you have viable. No Captain recognizes the name Kurosaki and no captains have come into contact with Isshin so the concept that they don't know him is false if they never met him. Urahara knows him and admitted being the reason for his lose of powers 20 years ago. Shinji said he didn't recognize his spiritual pressure so he may predate Shinji's time or he may have come after his time, who knows.

5.) While Isshin maybe powerful its highly doubtful that he has power anywhere at the level of Yamamoto and theres nothing to prove what his power is currently.

6.) Your all over the place with Ichigo. Its real simple he is a Vizard/Human. Yes we use Shinigami but in name only he has passed that a while back. If we use Shinigami/Human its with the understand that he is unique the series being of two worlds the living and the dead. Vizard being both Shinigami and Hollow the two worlds of good and bad in the world of the dead and then human in the world of the living. There is remotely nothing that being a human has ever done for him except make him more intouch with his emotions and thats not a power and those humans with powers all have spiritual powers to fight as he does, except he has his own.

7.) There is only 2 levels of Zanpakuto (Shikai, Bankai). Ichigo is not the only wielder of a Zanpakuto in the series. Each character at some point whether we see it or not has gone through advancement with their Zanapakuto but that doesn't factor in anything special. Its a personal issue. Its like training and development. Some do it faster then others and some dont at all. A zanpakuto is part of the wielders soul but it is a separate individual a true partner. Every wielder has to learn the name and learn the techniques. What you list is development points not power. Zangetsu is the zanpakuto spirit one and all not a part it is it. Ichigo has a constant release zanpakuto and therefore has no sealed version the sword he had originally is a product of Rukias power that he had not his own.

lastly movies aren't canon anyway so it wont matter what happens in them.
