It could even become a periodic community discussion/vote on who to add, and each time one is added it may end up provoking some pleasant nostalgia and discussion with the community.

Criteria to be in the the list has to be thrashed out, it's really the thing you need to start on before you can add the people to it. If you are having trouble finding the criteria, look at the dead-certs you've got and consider why they're there.
