When the the 787's do eventually replace the 767 fleet, I'd expect the seniority of that flying to go up. We will be parking a lower paid aircraft with one that pays much more. I'd imagine that there are many people who don't want to fly long haul while sleeping in a Polaris seat for only $14/hour more than a 737, but would probably be willing to bid a comfortable plane with an actual bunk when the difference is $87/hr.
