This is a really great proposal.
I agree with the strategy of using a 3/5 multi-sig.
I think some good contenders would be: Gauntlet, Chaos, Llama, BGDLabs, Morpho and/or Fig.
My only question is how much should they be paid – this will depend on their scope. If they are high impact / high urgency only, then probably less, but if they are low impact, incremental decisions (what Chaos is proposing), then probably more.
What Chaos is proposing in this thread is that low, impact incremental changes also fall under the scope of the Risk Council – I think this probably makes sense assuming that the changes fit very well-defined, DAO-approved criteria and the changes are communicated on a transparent basis (the current state of affairs is that governance is bogged down with parameter changes that take too long to change and usually always get 100% “yes” rate). Any DAO vote should override the Risk Council’s decisions.
