Dividing people would only bring in profit if you were selling them to humanoid eaters. In which case you might as well divide cows, less illegal. You won't get any great super soldiers because one divided person is always a weakling and the other a psycho with an expiry date.
The real beauty would be in the blending. You blend a Klingon and a Nausicaan and you stick it in stasis, only waking it up when you were ready to point it in the direction of who did this terrible thing to it.. or so you say.
