Would you feel different if the cloned body (or body parts) were grown in a fashion such that it was never intelligent or aware? Such as without a full brain or even without a head? Would it then be a soul?
Thats why I didnt want to mention that or answer to loup. I didnt not wanted to end up with religion debate on whether there is God and Soul, and if Soul can be transferred etc. This was pure speculation on how to live forever. That is, if you could live happily ever after knowing you tricked your twin-brother/sister and gave him falling apart body with a 5 years life-expectancy.
We are getting really into science fiction now. Perhaps if you could somehow monitor and capture every single signal sent from human brain to its body from the moment brain formed itself (I know there is a flaw here...), then if you could record that transmission for 25 years, perhaps (Im really in year 2350 now, I think) you could program a computer that would re-play that transmission into a growing body (to mimic brain) and as a result at age 25 had a healthy body without human brain. This, I think, would cut-off all skeptics that believe Soul is attached to mind, not body itself.
Maybe I shouldn't have use the word "soul". My vision is, we do not have souls, we are souls. Body + Brain = Soul, so to speak. Death is when that soul is irrevocably destroyed (meaning, even the information required to reconstruct it is lost forever).
So, while convoluted, your solution sounds like it is acceptable. Be careful however to play a record of a past life, instead of, say, actually simulating a brain in a silicon chip, Gunm style. Because that simulation would most certainly be a soul as well (I don't believe in philosophical zombies).
