The KIA (King's Indian Attack) represents an interesting way to gradually adopt a 1.e4 repertoire. Play 1.e4, if 1. ... e5, then you learn to play the lines you want to play in the double kings pawn domain, but if you see 1. ... c5, or 1. ... c6, or 1. ... e6, then you play the KIA. True, that's not the best line against every variation in the semi-open games, but it'll get you through while you learn the double kings pawn lines. Then, you gradually pick up lines for the semi-open games. But if you're interested in transpositions to Q-pawn lines, I don't know much about that. I defer to others.
1. Nf3 openings...
If you want a QG, why not play 1.d4? I mean, they can play the Indian games, but 1.Nf3 doesn't stop that anyway....

Sometimes QG players play 1.Nf3 to avoid certain lines by using transpositions. There are many ways to utilize this, especially if you know a players openings.
Thank you for the response catalyst, I appreciate your feedback.
1.Nf3 can be used to avoid the Grunfeld. I guess you could do it with a 3.Nf3 QG setup, but I was just looking to get a different spin on my repertoire is all, I'm already a 1.e4 player so I thought that 1.Nf3 would fit in nicely.

1.Nf3 avoids the main line of the grunfeld, but not the 4.Nf3 variation, which can be transposed into with 1.Nf3 Nf6 2.d4 g6 3.c4 d5 4.Nc3 Bg7 5.Bg5
1.Nf3 can definetely used to avoid the Benko gambit. there are probably others too, thats just the one i thought of off the top of my head

If you're going to play 1.Nf3 Nf6 2.d4 and (I guess) 1.Nf3 d5 2.d4, then I don't see an advantage over 1.d4 and 2.Nf3.
However, there's the Anti-Grunfeld line 1.Nf3 Nf6 2.c4 g6 3.Nc3 d5 4.Qa4+ Bd7 5.Qb3 where black's Bd7 is supposed to be misplaced.

ya there really isnt much advantage by changing the move order.
in a unrelated question whats wrong with 4...c6 in that grunfeld line?

5.cxd5 Nxd5, and now both 6.Nxd5 Qxd5 7.e4 and 6.Qd4 score well in the database. (I don't really know these lines, so that's all I have to go on). Either way, black doesn't get a Grunfeld.

Vladimir Kramnik has used usually 1.Nf3, I don't know what about today.
1.Nf3 take away 1..e5 which can occur by 1.d4 e5. If you like to fianchetto your bishop g2, especially King's Indian defence, don't play Nf3 at all. Excample of KID
I was wondering if there are any good resources about building a white repertoire around 1.Nf3. I would like to transpose into Q gambit lines or even a King's Indian Attack. I know that there is a Openings for White according to Kramnik but this is way over my head. Any suggestions?
