I also imagine that Malack alone meeting the order would not end up in a fight. He would chat with Durkon, explain that he doesn't care about what the rest of the Linear Guild is doing and has no desire to fight the Order, and probably part ways amicably.
I don't think Malack has much interest in fighting the Order, but it won't be that simple. I can't see them just letting him go like that. The other possibility is that Malack meets up with Vaarsuvius, who doesn't seem in the mood to fight either.
