The dark council wins with their plethora of combat/skill feats

In FotJ, Luke can enter some sort of super saiyan state where his cells seem to glow bright with energy, and all he needs to do is to call upon his love for his family/the Jedi/the galaxy or some shit like that. At that stage, he's able to drive away Abeloth.
Even discounting that, seeing as how Luke can rend himself literally immovable, I don't see how the Council can hope to affect him telekinetically. Force lightning isn't going to do much to him if the Reborn Emperor can't overwhelm amped! DE Luke with his, and his can light up planetary surfaces.
Luke, meanwhile, can easily ragdoll them, given that he's immobilized Caedus without even gesturing, or he can oneshot them with electric judgment, seeing as how he was able to one-shot Force immune Slayers, a single sick one of which could gain the upper hand against Kyp Durron. Gradually their numbers will dwindle. They can try to engage him in melee (or perhaps the decision will be made for them), but Luke's saber swings are so strong, they can cut through lightsaber resistant Vong armor, and so fast that Leia can't even perceive his movements, so it's unlikely that they could even tag his swings or withstand them without getting their arms broken. They all die in a heap, and pretty much last as long as Luke wants them to.

He needs a nexus for everything he does. If you place him on a neutral planet like Earth, Vitiate would probably insta-die. My dog > Vitiate.
On topic: each member of the Dark Council is canonically better than Malgus, who is canonically better than 4 of the protagonists. So Luke is fighting the equivlanet of 12 Malguses or 48 Noxes/Wraths/HoTs/Barsen'Thors... Luke gets murked. Any member would soloeasily
