I think that this Q&A with Sir David King, chair of UKs Independent SAGE sums up the end game of such an initiative. https://www.independentsage.org/qa-with-sir-david-king-chair-of-independent-sage/

When asked why he felt the need to set up the Independent SAGE since the government already had its own advisory body, SAGE, to deal with emergencies, he answered:
“Because there is no transparency about what the government is doing, no open discussion whatsoever.”

“At the start of the pandemic, the membership of SAGE and the minutes of its meetings were kept secret. During our first public meeting in May, the minutes of SAGE’s first six meetings and the list of members were published with a few redactions...”

“... (Dominic Cummings’ name was removed). We embarrassed them into going public.”

A key part of Independent SAGE’s mission statement is making scientific expertise accessible to the public. Why is this so important?
“First of all you have to bring together the right group of experts to give advice on how to handle an emergency.”

“But the most important thing we do is to have open, public meetings. We produce draft reports before those meetings and then we change the reports based on the to and from between the public and the experts. “

“For the experts to hear what the public have got to say is absolutely critical and in that process you’re improving the advice you’re giving to the government.”

“But there’s something else very important that you’re doing — you’re gaining the trust of the public and that’s what the government has failed to do completely.”

A very important point is that inevitably, some or all advice will be ignored by the government. To this, Sir David King says: “There was a point earlier in the year when we were saying, ‘Use the summer to manage this epidemic, try to get down to zero Covid, ...”

“... with a fully operative Find, Test, Trace & Isolate system’, because we knew that the winter months were going to be really difficult, and the advice was ignored and here we are going into a second wave. It is incredibly frustrating but we have to just carry on.”

“In each case I’ve always told my colleagues ‘Don’t look backwards, we’ve got to take where we are today and give the best possible advice going forwards’.”

And about the fact that a short term enterprise is still needed months into the pandemic: “We didn’t expect that we would still be needed after three months, but here we are. I’m extraordinarily proud of this group of people, who are all world experts in their fields. “

“They all have tough day jobs and the work they have put into Independent SAGE has been quite remarkable and they are not paid a bean for it. But it’s a question of public responsibility. “

“We will keep going until we feel that our advice has been taken and as a result the disease has stopped spreading. We will keep going until there is an end in sight and that end has to be a zero Covid Britain.”
