Unfortunately, inserting complex novel gene sequences into every cell of an organism in a way that doesn't just cause massive, global cancer is very hard problem. Making those sequences do what you want them to do, and not, say, kill the target organism is even harder. Especially since human anatomy isn't well suited to the task, and would need to be modified. By the time we have the technology to do something like that, death is probably already a solved problem.

That said, I've used the premise in a science fiction book before. The main characters were members of Homo Sapiens Durabilis, and had genomes modified with tardigrade genetics. They could be pumped full of hydrogen sulfide, and reversibly dehydrated to death for long-term space travel, or during a medical emergency.

I didn't find any amphibians which survived complete dehydration, but I found an insect.

The useful word is anhydrobiosis-- but no amphibians are mentioned.

In Russia and China one can be shot for being different.

I think you might need to update your beliefs about Russia. The ones you seem to have are stuck in the 1930s-1940s.
