The thing about Bleach is when you look at it through the prism of a Nippon Ichi Netherworld it starts making perfect sense. The Court of Pure Souls is basically Celestia. The difference is that instead of being Prinnies they just make the place so generally oppressive that the rank and file populous wills themselves into reincarnation. Basically, Bleach takes place in one of those other Netherworlds... Meaning Bleach is about a purgatory. Bleach is pretty blunt about Hell being a real place... and that few people actively deserve to go there. I think it comes up once in the entire series. This basically mean that actually going to Heaven or Hell is extremely rare... meaning that if you add in the wonkiness of the timeline and constantly changing backstory bits are an active disinformation campaign by Yamato... basically all series starts making logical sense.
Ichigo ends up as someone being groomed for the Overlord position.. and in typical Bleach fashion no one is going to tell him this. The sheer amount of situations he ends up resolving alone mean he is a shoe in after a century or so. Really Bleach keeps making reference to how almost no one ever avoids passing on enough to stick around the Court of Pure Souls into their second century.
So it wouldn't be so much a bill to get to the human world so much as some other human world. Netherworlds are altered by the raw belief of the living populous. Which is why Lahral's Netherworld is its own planet and he has the level of power he does. The Court of Pure Souls is likely just an eastern Asian branch of the local Purgatory. Not that you have clearance to know any of this.
