Thanks for all of the very interesting answers. In May, I'm participating in an open in Denmark where Demuth will be playing as well. I  could ask him about the book if it hasn't been published yet. It could also be worth a shot getting Jones' book on Lb5 as it can be tempting transposing into the sicilian.

Khalifman/Kramnik 1ed 1 Nf3 transposes mainly to mainline QGD, 2ed Khalifman changes to the Catalan but did not complete the series (ie vol 5 was never updated).
But it is not a Reti-based/inspired repertoire.
If a fianchetto-based White  1 Nf3 repertoire is the goal and depending on your playing strength, then there is the compact (relatively speaking) Wojo's Weapons. It is also Catalan, fianchettoed KID and Grunfeld-based but you may or may not like Wojo inspired lines.
After dabbling and looking at a 1 Nf3 fianchettoed-based repertoire for many years (on and off) but probably not to MAyton's or TonyRo's experience or strength, I don't think there is any good books available. You have to compile yourself from various books. I think you also have to have a certain mentalite to play the Reti-based 1 Nf3 repertoire as White. It is very much a strategical middle game and endgame kind of chess where understanding of pieces and plans is more important. I have discovered that I have yet to gain much of that understanding and hence not very successful in playing this kind of repertoire.  I am still trying for fianchettoes from both sides.
Of course OP may be very much a stronger player than I and therefore may adapt much quicker.

So far the following books have been mentioned:
Khalifman/Kramnik 1 Nf3 5 vols (or 10 vols 1 ed and 2ed);
Marin's English (3 vols);
Wojo's Weapons (3 vols);
Delchev's Reti (1 vol but only Slav and Anti-Slav)
Lemos' book (I vol)

There is also Gawain Jones' book on Bb5 Sicilian but he provides KIA lines as part of the repertoire.
And there is also Neiman and Shoker's book, full of ideas but confusing (Sadler thought so in his review in NIC mag).

Other books (much older but I think still useful and usable) which may provide some ideas and specific lines:
Donaldson's book (1 vol 2ed)
Keene's Flank Openings (1-4ed)
Duncan Suttles' Games (3 vols)
Dunnington's Reti (introductory)

What do you prefer against 5...d5?

Sounds like an interesting idea with 2. g3. I have Avrukh's old book on the fianchetto solution against KID/Grünfeld but surely he will come with an update of it.

Lemos puts the king's knight on e2 in some of the Grünfeld lines. But maybe you're avoiding the Grünfeld with 1.Nf3 anyway. His King's Indian Fianchetto stuff is still relevant, though obviously less deep than the coverage in i.e. Avrukh (for White) and Kotronias (for Black).

Thanks for the information. This looks like tons of theory. Maybe the following can be used:

1. Against QGD the neo-catalan as described in Marin.
2. Fianchetto solutions against KID/Grünfeld; I could imagine that the Lemos book is good.
3. Marin solutions against symmetrical/e4 in the second move.
4. Use Marin against the Slav.

Then there is probably 1.Sf3 d5 2. c4 d4 for which I need a weapon; perhaps Delchev.

It seems to me that there aren't very many books on the Reti opening seen from white's perspective. Delchev has one but that only covers the anti-slav. I'm very fond of Marin's books on the English but 1. Sf3 avoids 1. -e5, and with 1. Sf3 you have have the possibility of transposing into the Sicilian after 1. -c5 with 2. e4. Using 1. Sf3 isn't so good with Marin's suggestions because he recommends the Botvinnik system with Sge2 against many setups. Of course, there are also down-sides with 1. Sf3 as you can answer it with -d5 but it would be nice with a good book on the Reti.
