Thinking about this overnight, my own hunch is sticking the "minimise all windows" button back in bottom-left (rather than the trash), and perhaps placing the trash back on the accordian.
This would re-use several years of existing muscle memory for swoosh-mouse-to-bottom-left-pixel-and-click (several operations per day/hour for minimise all vs. several operations per week/month for trash).
