This is missing the forest for the trees. You'd want them represented accurately at a local level along reasonable district lines, rather than intentionally being misrepresented with district lines so tortured that the shapes they make are said to resemble a lizard. Maybe that's hard but I suspect it gets a lot easier once the bad-faith decision-makers are removed from their decision-making power. In the context you present, "competetive districts" means precisely the same thing as "representative outcomes".
