Actually under the definition you just defined, the KID and Grunfeld synergize ie when someone plays a move order to prevent the Grunfeld the KID is still a playable alternative.
Well it's true you can start with ...Nf6 and ...g6, intending a Grunfeld, and then switch to a KID. But I don't think you're getting "superior" lines of a KID, like you (arguably) are when playing 1.d4 Nf6 2.c4 e6 3.Nf3 c5 or 1.d4 Nf6 2.c4 e6 3.g3 c5, for instance. What lines do you have in mind? In the Grunfeld, Black commits his pawn to d5 as soon as White plays Nc3, so I don't see how you could use the KID to avoid, say, the Bf4 lines, the Qb3 lines, etc.
I suppose I could agree that you have the option to play the KID against an English move order, like 1.c4 Nf6 2.Nc3 g6 3.e4 d6. But I don't think this synergizes in the same way as the examples I gave earlier, because White still has his entire range of options to throw at Black (except, perhaps, some fianchetto lines). I don't see what advantage Black has gained, unlike in the Nimzo/Benoni when you can avoid the Taimanov attack, for instance.
