Apologies if someone mentioned already, but I think fully-proportional apportionment by state popular vote is a good way to assign electoral votes as opposed to our current system. It makes the EV much closer to the popular vote, which is general good for democracy, but maintains the normalization factor of the EV system that prevents political dominance of every issue by voters in NY, TX, FL, and CA.
Also, do away with electors as a concept if people aren't electing them. I get that Madison saw the electors as a control on the federal government, but in the long-term, it enshrined the ability of a group of unelected elites to reverse the will of the people. Right now, state party leadership (which is also generally unelected) select their electors, and most of them are state legislators or local politicians or party leadership cronies. If your state legislators are anything like mine, that should fucking terrify people.
