consider making similar arrangements and then have the legal mechanism in place to resume ownership (of at least part of the funds) if some re-animation would be possible in the future.
What if they re-animate you as a head in a jar? Do you get to spend your bitcoins on fancy fish food, or a fancy jar that doesn't double up as an ice bucket for beer?


feeding my brain in a jar would be easy; just sprinkle in weed every so often.
