Realistically, the only way to make everyone happy is to lock each character to one lockout a week. It used to be this way in Wrath - You either did Heroic, or you did Normal. The bosses you didn't complete on Heroic could be completed on normal if you were in the same group as before. (The later restriction would not be an issue in this day and age.)
And yes, that includes LFR, even though that would literally be the death of LFR as we know it. There'd be plenty of players doing LFR - But the question is, without normal, heroic, and mythic raiders, could LFR heroes on their own manage to finish content?
