An alternative might be a collection of states banding together to solve how they send members to the electoral college. "First past the post" versus "representative" (versus fancier, better options, like run-off voting) is a state's right under the constitution.

Current first-past-the-post states are incentivized under the current regime to stay that way because it makes for more opportunity to be treated as a "ballroom belle" ("swing state") each election cycle, which brings money and attention to the state it might not ever see otherwise.

It's possible, though sadly unlikely, you could fix the current regime by fixing things from the bottom up at the state legislature level, one state at a time if need be.
