This is a very nice idea which triggers my interest. One thing i noticed is that the gsxr counts cilinders the other way around. Cilinder 1 on the K3 is next to the timing chain, on the gsxr this is cilinder 4. Both engines turn the same way, have in- and outlet on the same side and ignite 1-3-4-2. So if you switch the ignition & injection between the cilinders (connector 1 on cilinder 4 and so on) than you won’t need custom camshafts and just make the head fit on the k3.
