Marrowgar easily.
Deathwhisper possibly (Control the casters from the trash before her for 20% haste buff), Kill the casters that spawn mid-fight and interupt / AMS Curse of Torpor.
Gunship I really doubt, but I could be wrong here.
Saurfang should be doable as well.
Plague quarter has been soloed.
Dreamwalker should be doable if you bring in a healer. (Might be an idea to use T13 4-set if you are having trouble with the enrage)
Sindragosa may come down to soloing it in phase 2, probably doable.
Blood council yes.
Blood queen, Possibly. You may have to kill yourself to get rid of the vampire bite, but that may lead to trouble with the enrage.
Perhaps rotating the bites with battle rezzes could work here.
Not sure about LK, I have yet to try it.
