So you think Aizen will become the new soul king, just because they "look very similar"?

Points that need to be taken into consideration:

1) Urahara stated that the Hogyoku rejected Aizen as its master. If that wasn't the case, why did Aizen lose his Zanpakuto and Hogyoku transformation(s)?

2) The Hogyoku has the ability to manifest the desires of those around it. If this is the case, why couldn't Aizen break free of Urahara's seal and escape the judgement of Central 46? (or Muken for that matter.)

3) Ichigo's theory about Aizen losing his power by his own volition. If this theory holds no validity, why did Aizen refuse Yhwach's offer to join the Wandenreich army to exact his revenge?
