Not exactly, because states don't have electoral college votes proportional to their population. Plus this does not address the fact that. when the electoral college was created originally, this population proportionality did exist, except that black people counted for only three fifths. So the system is inherently racist, plus it is not adapted constantly to changing population numbers. Your idea would not fix either of that.
Has it ever been calculated what your idea would result in? I"m wondering if it would even make electoral college votes comes closer to the popular vote percentages?
