Separate display on each screen?

I'm willing to believe that macOS just doesn't allow it, but would it be possible to have different icons shown on each monitor? So that instead of icon-per-monitor showing "3 11 16" on all displays I saw "3" in the first display's toolbar, "11" in the second, and "16" in the third?

Late to the party here, but this isn't possible as far as I'm aware, as the menu bar is shared across displays.

I tried to implement it in WhichSpace, but the best I could do was update the menu bar when focusing a display.
