I don't think that writing yourself into the future would work very well, but I've got another idea for a cheap cryonics-substitute: get your brain frozen in plain old ice. By the time we get whole brain emulation, a brain frozen in ice may contain enough information to replicate on a computer, even if it cannot be biologically revived like a cryogenically frozen brain.
Permafrost burial has been explored, but is generally considered an inferior option. If I were going for a cheap cryonics substitute, I'd try plasticization. A lab can do a head for a couple thousand bucks, it preserves enough microstructure for an electron scanning microscope, and there's no worries about staying cool.
