Well, technically if its no Force powers... then neither one of them would be able to handle a lightsaber correctly and use it in combat, because Jedi, Dark Jedi and Sith need to use the Force to wield a lightsaber and face another in combat. So... since there are no Force powers, I'm assuming they are not using lightsabers either, therefore, it would be a fist fight. So its a wimp verus and old man.... hmmmm, I say Luke takes it after a tough battle...
There's a difference between no Force powers and no Force. powers are just using it in a form you can identify sorta, but letting the Force work through you is a different matter.
As for the fight, this is only 5 years after the battle of Endor so I say Dooku.

Jedi Outcast is eight years after Battle of Endor and between that time Luke was able to beat the Darth Sidious's clone, which has Sidious's spirit inside, so I'd say Luke could take Dooku.
So you like splitting hairs? Well, you see, in the ROTS novel it says that GG can move faster than the human eye can really percieve due to his mechanical limbs and training from Count Dooku. Take Jacen Solo, for example... when he cut himself off from the Force in Balance Point, he found it very difficult to use his lightsaber affectively in combat.
Emperor Revan- Good point with the whole Force power and Force thing, didn't think of it that way.
