Thanks Kostas,
Took me a while to see it, then it seemed so obvious.
Fun challenge!
ps: you can make a h#3 out of this, with only 1 cookstopper (which preserves all of the Royal Queen's mobility, after the 4th ply):
 (= 4+5 )
h#3  = Royal Queen.
Black's play is rather dull, but the extreme mobility (after the 4th ply) seems quite paradoxical; and, white's play is not bad.
It would be nicer to expand this to h#3.5, starting with 1...Bh8, for an Indian theme, but there are many cook issues to overcome (especially Rh8#).
A well placed white Royal Pawn (or some such, which doesn't interfere with the mobility idea) might help save the day; but, I'm not optimistic.
Maybe hr#3.5 would help it along (or h-semir#).
But, since this is idea belongs to Arno & Hauke, I'll happily leave these challenges for them to ponder. :-)

@Kevin & Kostas: Yes, and this is exactly what I (and obviously also Hauke) had in mind when posting post 3 above...
Only that I had a wRh2 and bPg2! Question anyhow: are somehow 23 possible?! Maybe Hauke has the answer...

@Arno,
Apologies if I have infringed upon your idea, here, but post 3 did not clearly specify that your queen wasn't moving.
You certainly were not ignored -- we simply failed to realize that we were on an intercepting line w/ your original idea.
ps: 23 is almost certainly impossible, if you insist upon a stationary queen (on black's final stroke). If the black queen can move throughout, things may be slightly easier.

There should not have been really any question about the meaning of post 3 because post 1 and 2 already showed that with moving queen you have all 27 flights and Hauke in post 1 clearly had asked for the number of moves if the queen does not move... Anyhow, still waiting for Hauke's response...

The Hauke is IN :-)
Kevin, since ideas are free (and I very rarely delve into fairy
area at all), feel free to use my "inspiration" in any way.
The (probable) case 2 maximum is tricky, although I should have
earlier recalled an old record using (nearly) exactly this gxf8Q
setup to mate the king on any free field on the board. And no,
I neither know how nor try to up the record.
Of course either color K are superfluous.

(can't speak for Arno, though ;-)

Arno has to confess that post 2 does not show any record as b7 is a none-flight... Shame on me! Even more shame if somebody still finds the 23!

Hi Arno.
My apologies, for failing to realize what post #3 really meant. By no means, I meant to ignore you, I just did not know that you were talking about the same thing.
In any case, I think the 22 moves deserved a diagram, since the main setup seems to be unique. I doubt more than 22 moves are possible

@Arno - amaurosis scacchistica collectiva. I believed it too :-)
sidenote @Kevin - regarding mobility, I once made a h#2 (I think
it's even posted here somewhere!) showing a bK getting all
8 flights in the first two halfmoves. I don't think that you
can pull THAT trick with a royal Q :-) Or a 23 move record, for that.)
