Qawi vs Kov is a huge mismatch. There's no scenario whatsoever you can paint where Kov wins. Saad and Eddie, Kov's chances are still extremely bleak, but I suppose a real pro-Kov fanboy could present an arguement. With Qawi, there is no argument to present. Kov wouldn't have a snowball's chance in Hell.
His only chance (a slim one) is Saad Muhammad. Qawi would absolutely take him into deep waters and drown him, and he can't even out-work a lazy fat Eddie Mustafa because he'd gas in the middle rounds
