You're right. So I would add one step. Go to a state (or a country) where the laws don't require autopsy.

For example, you can sign a "Religious Objection to Autopsy" in these five states: California, Maryland, New Jersey, New York, and Ohio (http://www.alcor.org/Library/html/certificateofreligiousbelief.html).

And of these five states, I'd chose California since it's near Arrizona where there's a cryonics organisation (ie. Alcor).

EDIT: or Ohio, since it's near Michigan where there's also a cryonics organisation (ie. Cryonics Institute).
