That's not really an easy question as a lot of it has to do with the feel of how it plays. If you want to give it a try, I'd suggest rare mace or axe main-hand and EF offhand. For the main-hand, you want as high of a damage range as possible, a socket and extra crit damage is a bonus. Both should have lifesteal as this lets you drop the IK belt for a Witching Hour while being able to deal with not using Rend: Bloodlust which will lose a lot of potency without the Skorn. In Rend's place, go with HotA: Smash to deal with elites.
Whether or not that's better will be up to you. You'll probably still like the Skorn better for farming white mobs and Ubers regardless, but you may notice smoother play with the two weapons, such as easier maintenance of WotB, less rubber-banding and less wasted time/damage with Bash / HotA.
