If we run All Quests, Current Patch, Co-op with the caveat that "You Will Die, Seriously" is not required, can a new category be made for that?

Just completed a walkthrough of Co-op All quests with my brother on current patch and planned to use the Morningstar glitch to finish Terra, but, after a half hour of stacking, it still wasn't feasible. We were both level 32 at the end playing Gaige and Axton. Is there a method to kill him without grinding? It kind of ruins the run if we are forced to grind levels or do an hour+ fight against Terra at the end. We're trying to avoid downpatching if we can, mostly because we don't want to.
