I don't have time to look it up right now, but a good starting place would be Kawasaki's parts diagrams. You should be able to find some exploded diagrams on both and see if they're anywhere close.
If I had to guess, I'm going to say yes on the pegs (those are the same from Honda to Kawasaki to Suzuki in some instances), maybe on the brake pedal (both are disc brake, it could probably be made to work) and I'm on the fence about the shifter lever. It's likely swappable, too, since all it needs to do is fit the shaft and be long/short enough.
