Will never work.

You can get stuff like this to work if it's pathetic and emotional enough (9/11 minute of silence, clap for essential workers from your balcony) and if it's low-cost (shutting up for a minute) or no cost (holiday). And that still is highly regional. Even "The West" are not that many people.

Sadly, your proposal checks none of the mark. Don't get me wrong, I don't think it would be bad or anything, but you know, people are people.
