If you go with the non-elemental route, you can perhaps make Steel Release an offshoot of the Asura Path of the Rinnegan - similar to how Shikotsumyaku is a derivative of the All-Killing Ash Bones.
Interesting chapter. The way the mechanics of bloodline limits were described seems quite plausible (especially the finishing touch of the world ultimately running on 'anime logic'). That said, what is the elemental combination for Steel Release in this fic? I don't think it was ever explained in canon.
Or... he fried his brain with constant memory surges...
'And this is just the regular Shadow Clone Jutsu, not the Multi variant that Naruto uses. This version can't create nearly as many, around five or six being the usual limit compared to the Multi version being almost limitless. But that could be a blessing rather than a curse. Because absorbing too many memories at once is extremely mentally taxing, you really shouldn't use that many clones at once anyways if you don't want to knock yourself out. I guess Naruto was just built different.'

I get that Bleach characters are pretty strong - but what makes you so confident that an actual Creation Goddess of an entire mythos is "weak"?
Okay, while I can agree that Yhwach might possibly be stronger than Izzy, comparing a Hollow with control over Decay with a goddess with conceptual authority cover Death itself - something much more fundamental in nature, literally makes no sense. Are you sure that you read Bleach carefully yourself? Barragan is very far from being an "Embodiment of Death" - not even Izzy probably qualifies for such a moniker - only characters like Death of the Endless from DC, and Lady Death from Marvel might deserve that qualification. Also, I'm pretty sure that Wilhelm spent a number of years in the Land of Shadows for his training - he definitely isn't a 'kid' even if you strictly consider his physical age and ignore the fact that he has a large fraction of the centuries of experience and memories of Zeltretch due to his reincarnation.
You do realize that neither Will nor Izzy has interacted with any of top powerhouses of Bleach on the level of Yhwach, right? There is very large difference in power between those with reality-warping abilities like fully-awakened Yhwach and post-Hogyoku Aizen, and the relatively 'normal' - if very talented Shinigami and Hollows. To me, none of the characters seems to have been 'nerfed'. Spiritual beings (Kisuke and company) being instinctively wary of a Creator Deity with domain over Death, hardly seems far-fetched.
I wonder if Hisoka would be more horrified that Yuna has followed her to her 3rd life - or feel more pity for Aizen when she learns of Yuna 'joining' his side...
Ehhh... Maid Cultist has already humbled the Mad Cultist methinks...
Nagato couldn't help but tremble in fear as he looked at the person radiating such deep madness that even Hidan would feel humbled.

It's probably even worse... it would be more like separating someone from the manifestation of their own soul.
Thinking about her situation, all she could think of doing was severing the connection between the goddess and the Noble Phantasm she had activated to make the domain disappear. For this to happen however, she would need to be able of getting close to her and actually staying her... and she didn't have much confidence in this plan.

Amazing chapter. Back when the Reincarnator reveal happened, Seija's parents' (especially her mother's) reaction was the one I was most eagerly anticipating... although I had expected to get to that point during their future reunion - but I am happy that my expectations were subverted for once!
