There is no 'problem'—or metaphysical uncertainty—when it comes to defining reality and what an individual is. The problem only takes form when you conclude with a subjective and rationalized view on reality. Existence is identity, and consciousness is identification. A man is himself because of the physical composition of his body and because he is able to identify his body with his five senses through the use of deductive and inductive reasoning (which are essential components to logic).
He is of a certain character or expresses himself through a certain personality because he is able to form and retain concepts, create value-judgments by integrating these abstract concepts with emotion, and he is able to confirm the external world and describe its nature through abstract thinking (time, space, science, mathematics & esthetics) but again, only through the means of his senses and cognitive faculty. Whether he wants to blank-out and deny the metaphysical truth of his nature or not is up to his free will.
Every man is his body as well as his thoughts. The two are not exclusive to one another. If anything, the body takes primacy over the consciousness because the consciousness is literally a part of the body.
As for your question regarding teleportation: No, if the body is completely wiped out at some point through the process of teleportation, then it means it has reached a point of non-existence. It cannot be brought back to be the same, uninterrupted form of life, even if the body and mind were copied into existence in another location; the original cells and bodily functions would've ceased to perform self-sustained and self-generated action.
I am a little confused on what you mean by partial stereotyping, because as a human, you cannot just be without thought and will succeeding it. If it were so, your existence, values, and ability would be the equivalent to that of an animal's. Automatic. Unconscious.
And finally comes one last question, even if you change 100% of your way of being, and forget who you were, did you die?
I'll come back to this question once I have rested. Very sleep deprived ATM. > <;;
