The democracy-by-jury opens up some pretty obvious problems. For one thing, having small numbers of delegates for the popular will is easy to undermine by altering the selection process for those delegates. I think you are better off trying to address some of the reasons why the existing system of delegation (i.e., rule by elected representatives) does not select good leaders. Eliminating gerrymandering through non-partisan districting is an obvious example.
