Working on it.

OK, I actually tested before I got your two messages, you're right and I was wrong.

It's now too big.

I guess I really do have to keep downloading these damn things.

This can be fixed by remastering. Really only two of seven images are worth keeping.
Index 1 and Index 6. Remastering depends on compression for results.

Using 7ZIP, I extracted the install.esd out of the ISO file. I renamed
this to installorig.esd to avoid confusion. Here, I copy index 1 and index 6
and pick terse names for the installer menu entries.

Administrator:

dism /Export-Image /SourceImageFile:D:\installorig.esd /SourceIndex:1 /DestinationImageFile:D:\install.esd
    /DestinationName:"W11Home64" /compress:recovery

dism /Export-Image /SourceImageFile:D:\installorig.esd /SourceIndex:6 /DestinationImageFile:D:\install.esd
    /DestinationName:"W11Pro64" /compress:recovery

I had to switch from "max" to "recovery" to get enough compression. "Recovery" compression seems to be
the same format as was used on the original ESD.

installorig.esd   4,056,557,808 bytes
install.esd       3,907,625,876 bytes   <=== it almost looks like is copies the solid block over...
                                              We may have saved enough this way. Just barely.

I create an empty directory D:\DVD and using 7ZIP, unpack the entire ISO into D:\DVD .
I navigate to Sources folder, delete the install.esd (== installorig.esd) that came in the ISO, and
put my home-made install.esd in its place. Now, the D:\DVD folder represents
the contents of my new ISO I want to make.

Macrium has an "oscdimg.exe" in its kits collection (if
you made a Macrium WinPE rescue disc). Macrium can use a WinRE.wim extracted from
your hard drive, if you allow it to use its default method. If you instead select
the custom method, of using a WADK kit, it downloads some stuff, including "oscdimg.exe".
Or, you can just download a WADK kit yourself (which may take a while).

Kari has a recipe for oscdimg that I used.

https://www.elevenforum.com/t/create-custom-windows-11-iso-file.443/

    oscdimg.exe -m -o -u2 -udfver102
      -bootdata:2#p0,e,bd:\dvd\boot\etfsboot.com#pEF,e,bd:\dvd\efi\microsoft\boot\efisys.bin
         d:\dvd d:\new.iso

This is what that looks like, copied out of the administrator Command Prompt window.

D:\>oscdimg.exe -m -o -u2 -udfver102 -bootdata:2#p0,e,bd:\dvd\boot\etfsboot.com#pEF,e,bd:\dvd\efi\microsoft\boot\efisys.bin d:\dvd d:\new.iso

That's a little bit less than the DVD limit :-)
Even remastering is getting damn close to not good enough.

Now, I have to test it.

I'll have to switch boot OSes and set up a VM for it.

Works fine.

Needs lots of cores to unpack the contents.
I ran the VM on two cores, and it was slug slow. Stopped
the machine, and kicked it off again with a few more cores,
and it was fine as far as these slug-slow installers go.

I used T [Todds] recipe of using

to get around having to enter an MSA. It would not
have mattered, the entry of an MSA, just the nuisance of
me finding the piece of paper with the details on it.
