I would do meetings with the most bayesian/utilitarian/imaginative/brilliant and cultivated people I can think of, asking them to invite whoever they think could be useful.
We would first discuss about what would be the best decision making process for the group; surely every decision could be made either by consensus or by vote.
Then we would take action.

Would you really not care about dying if you knew you had a full backup body (with an up-to-date version of your brain) just waiting to be woken up ?
