Can cellular replacement based on embryonic copies explain the longevity of elves?

In my research on how I could get elves to live the time spans I wanted them to live, I came up with this solution:

Every elf generates while still developing inside the womb of the mother copies of his embryo which get stored somewhere in his body. Each time the elf reaches its equivalent of 60 years (human age) a hormone causes one of the embryos to share its DNA and within the next 3 to 4 years the elf gets his whole body replaced by the young body code the embryo has stored. during these 3 to 4 years the elf is very vulnerable and will sleep 90 to 95% of the day (the rest he will eat and drink)

The Brain will be preserved by saving the connections the synapse had and connecting the new synapse in the same way. Let's say this works with 85% accuracy and always for the important part (close relatives, partner, values/character).

This can be repeated to arrive in edge cases 1 out of 10 million at 6 000 years. Most elves only reach about 350 to 600 years. Oh and mutations of the embryos are kept in check by comparing the embryos. Let's say only 1 of 1 million mutations gets activated per embryo.

Now I wanted to know if this is feasible or not.
