Needless to say, I disagree. Like Mountaintimber said, I've sourced and cited the manga multiple times in this document  and essentially everything you offered here is already refuted there. But if you're not interested in reading it I'll summarize my refutations to your points:

"1. Alluka and Nanika are suggested to be 1 male and the other female"

Incorrect, covered in the document. While I personally believe Nanika is at the very least female-aligned, Nanika is at no point gendered in the Japanese text - all instances are inserted by translators for the sake of acceptable sentence structure in English. (Before anyone brings this up: The line where Nanika purportedly asks Killua if she was a good girl is a flagrant mistranslation. What's actually being said is a stock request for praise in the form of head-pats.)

The only indication that Nanika is female is based on the connection with Alluka. Nanika does not use female pronouns (Alluka uses the female "atashi"), and she does not use feminine speech patterns (Alluka does). Nanika is never called a girl by anyone in the entire series. Also cited in the document are literally dozens of (probably close to 100) comments by Japanese fans stating their belief that Nanika is a boy while Alluka is a girl.

While Alluka is quite clearly considered a boy by the rest of the Zoldycks from her birth, the narrative itself (outside of Killua's statements, which are otherwise considered and proven to be correct) indicates that Alluka's gender is female no matter the state of her body ("physical sex", so to speak). I talk about this in the document with the title of Chapter 322. You can hit ctrl+F for 322 if you want more details there. I covered it pretty thoroughly.

It's been stated (and pointed out on this wiki, and is even mentioned on Alluka's page) over and over again that Silva, Kikyo, Illumi, and Milluki are consistently wrong about Alluka and Killua's track record is 100% accuracy. Like I say in the document, if there is a point where Killua clashes with his family over a detail regarding Alluka, he is always the one who ends up being right.

I should note that Killua doesn't say Alluka is "female", which I think you might be arguing? I'm not sure what you're trying to say there. Killua says she's a girl, not that she's female. Though I consider it to be a little unfortunate, I won't deny that it is common for transgender women to be considered "male" (and for transgender men to be considered "female") in regards to sex.

Basically no one (except for one exception that I already refuted in the other thread) is arguing that Alluka is a cisgender girl at this point, it is pretty obvious that she isn't. This doesn't mean she's not a girl, though.

"[...]  while it's also pretty clear that Alluka view themselves as female [...]"

How is this not reason enough to use female pronouns? If you believe Alluka considers herself to be a girl, should her own implications of her gender identity not trump everyone else's opinion excluding Togashi's? This is a matter of accurately reflecting Alluka's own personal pronoun.

" 3. Alluka was designed to be gender-ambiguous through and through, it's a part of their integral characterisation and design."

This is speculation, and it's speculation that there is more than sufficient counter-evidence for in the actual text of the series. Togashi has at no point stated that he intended for Alluka to be a gender-ambiguous character - if you have a direct source (including the original Japanese) saying otherwise, I'd be happy to step down on this matter. However, I've been literally scouring the internet for interviews with him for weeks, and there has been nothing even resembling a statement like this.
