No, Aizen cannot Reiatsu crush the Narutoverse.
Reiatsu crush has never been put to the test against other forms of energy such as Ki, Nen, Chakra, etc. We can't say that it'll work on these kinds of energies because these energies can be used to coat a user in protective aura which the Reiatsu will have to overcome in order to affect the person to begin with.
Not to mention, we know that Chakra is related to spirit in Naruto. Not only do a lot of translations translate Sakura's description of Chakra to "spirit" (although some translate it to "mental"), but Naruto characters have the ability to interact with souls as has been shown on numerous occasions. When the Edo Tensei of the Fourth War was undone, the Shinobi Alliance interacted with the souls that were ascending. Sasuke interacted with Itachi, Choza interacted with Dan, Naruto interacted with Minato, etc. etc. Naruto has also shown the ability to actually pull his own soul back to his body (as shown when he fought Nagato) in a manner strikingly similar to the Chakra tug-of-war he had with Kurama. We also have instances such as Hagoromo coming back to life literally as a ghost and the previous Hokage being able to see him and talk to him. You really cannot compare Naruto characters to ordinary Bleach fodder in this department at all. It has its fair share of spiritual feats.
And to put the nail in the coffin:
"Kuchiyose Gedou Mazou
Everything is snatched away by the Outher Path's Giant Dragon whirling about!!
Kuchiyose Mazou is the container for the Bijuu chakra, it works as an enslavement jutsu. A dragon is released from the Mazou Kuchiyose, it possess enough power to absorb the Bijuu chakra, with a mere touch ones chakra sticks too it. It's different than the normal summoning blood contract, instead the jutsu user runs the risk of having their life absorbed. Nagato successfully used this Jutsu, because due to his clan's bloodline he possessed a large amount of life energy.
One touch the chakra instantly sticks to the raging dragon."
Fourth Databook page 247
The bolded is referring to Nagato's spirit dragon which he used to defeat the Amegakure shinobi: (We can tell that it's referring to this dragon because it only makes reference to this one dragon and not the nine phantom dragons, and it also mentions that the dragon is "raging" and mentions the fact that the user runs the risk of having their life absorbed, which all describes this scene perfectly)
This means that the "souls" we see getting ripped out of those shinobi is actually also Chakra. Don't think those are souls? Look at the Human Path in action (this is confirmed to rip out souls in the databook and Manga):
The fodders' "Chakra" and Shizune's soul literally look exactly the same. That pretty much confirms that Chakra is related to soul.
