Outlandish Brain Resurrection Proposal in Tier 2 Vocabulary

Prompt

For those looking to attempt long term storage of their body/nervous system in hopes of reviving themselves after death, it seem they often focus on preserving the body and/or brain as it is, in its entirety. The issue is methods either effectively embalm the brain, or in cases such as freezing the cells of the brain burst open and destroy the cells. My question is: why bother saving the contents inside the cells at all? If the person is the working of the network, the person is the neuron components which conduct the electricity. While extremely complex, the inner contents of the neuron cells are theoretically able to be manufactured, including the same mitochondria and the person's DNA. Why not drain/empty the cells, preserve the actual network of the brain, and then aim to reconstruct the brain by "refilling" the neurons? No burst, no major damage. Evaluate this concept and answer that question using the latest medical science.
