1. Bane has a double-bladed lightsaber? Hmm... well, Kas'im could take out Ulic after a long duel. Bane with a saberstaff is unknown - he knows all the movoes of a saberstaff but he never used one before. If he had has single-bladed lightsaber he could win, even without armor, though with difficulty. Is Bane allowed to use just one half of his double-bladed lightsaber? if yes, he beats Kun, if no, I say Kun beats him after a long duel, same time as Kas'im beats Ulic. Then it's Ulic vs. Kas'im... could go either way, I'll say Kas;'m would win. So Bane and Kas;im maybe take this, but I'm really not to sure.
2. Can Kun use his amulets? If yes, he takes out Kas'im right away. By his prime Bane is probably a master at that atatck he used on Kas'im in PoD. He kills Ulic with it, or else Ulic is able to block it with a Force Shield, not sure. Then Kun shoots his amulet at Bane, kills him if it can go through Bane's armor. if not, he aims for his head and Bane can just move his head to the side and dodge it and likely best Kun. So there's a lot of unknown things here that could easily decide the outcome. Really not sure.
3. Bane in his prime is still likely ahead of Kun, even without armor, and Kas'im could at least hold off Ulic till Kun dies, and could likely beat him.
4. If Kun takes Kas'im and the armor is able to block the amulet, Bane beats Kun, then helps Kas'im destroy Ulic. If Bane takes on Ulic, then UKas'im gets blasted with the amulet and Ulic and Kun togther beat Bane. I'd say usually Kun would take on Bane, since they are the strongest of their team's, so it depends on whether or not Orbalisk armor can block amulet blasts or not...
In other words: 1 is Kun/Ulic, 3 is Bane/Kas'im, and I'm not sure about 2 and 4.
