For this idea, you have to assume that either A) it has already
been done, so that you really will not be changing anything, or
B) you can somehow copy a person's consciousness without
interacting with the matter making them up at all, so as not to
introduce any disturbance. The first seems too convenient, and
the second unlikely, IIU quantum mechanics correctly (and I may
not...).

If you are interested in a fictional account of exactly this,
read Spider Robinson's _Deathkiller_. A sequel, _Lifehouse_
was written, but is much poorer, IMHO.
