If you change the intrinsic spin of a particle, it becomes a different particle. E.g., an electron has a spin of +/- 1/2. If that spin is somehow changed to 3/2 or to 1 or 2 or something, you no longer have an electron and instead have something else. Also, if orbital angular momentum and intrinsic angular momentum can go back and forth like this, I presume there has to be a corresponding change in spin (intrinsic angular momentum) in another particle involved in a scattering?
