So, after messing around in the KH3D demo for the umpteenth time, I discovered that is possible to have all your Dream eater allies Killed off for Real. And as far as I know, the only way to get new Dream Eaters is through synthesis. I dont know how vital the abilities you get from the dream eaters are, but it would be conceivable( or at least not maddening) to do a No-Dream-Eater run of KH3D?
