It will create false data that will be seen as noise at all ISO values.

The AA filter has nothing to do with "shoot noise". There are multiple sources of noise in digital images and none of them are called "shoot noise".
The AA filter and sensors have nothing to do with protons.
Digital image noise is not "the uneven distribution of protons" or even photons.
Stoffer wrote: On the other hand the advantage of capturing every detail could result in the side effect that one can apply more luminance noise reduction without losing critical sharpness.
You are not "capturing every detail" by eliminating the AA filter. You are generating false data (by the aliasing of spatial frequencies). You can't apply noise reduction to eliminate the false data because it replaces real image data.
In any case, if you are using a Nikkor or Zeiss lens you are unlikely to be using or be able to afford a lens sharp enough that it does not act as the Anti-Aliasing filter itself.
Stoffer wrote: What are your thoughts and / or experience regarding high ISO noise and a lack of AA-filter?
I think you are in over your head in an area that you have no understanding of.

It doesn't work like that.
