Equipment Suggestions Needed

Um...not sure what you mean exactly by a Zen setup, but what I meant is "Zen Harmony"

Yep, I knew what you meant, and that's what my comments apply to.

A Zen, with his fast recovery, has basically two advantages: being back to swing his sword as fast as after blocking with a shield or (and this is important) walk away from a mob of angry monsters, since it's much harder to get him into stunlock.

The problem you face with your original variant restrictions is that pretty much everything will hit you since you won't have any useful Armour Class. You've given up shields (which can carry some armour, resistances and hit points) and the highest +life modifiers, so you'll also be somewhat limited in how much life you'll have.

It'll work in Nightmare, you'll see how, with all three suffixes, you'll be able to face small mobs without much problem (other than drinking much) and be able to walk away if more enemies come to you before you're done. It is quite noticeable. In hell, though, you'll find yourself go splat unless you are very very careful with how many enemies you wake up. Being able to run is not very useful when you can die before you turn around to do so ^_^
