If you don't want me to do it I could just not.

Nope. Just Haki, nothing else.

Luffy in Gear Fourth still wasn't even close to island-busting levels. Although it would most likely be an interesting fight to see.

Probably the more powerful enemies would be able to face him, but he's at least beyond most Warlords. Doflamingo was exceptionally strong, while the others weren't nearly on his level. Characters like Crocodile wouldn't last more than half a second against someone in Enel's league of power. And I'd argue that Enel would stand a good chance against Doflamingo if he started out with a full-power attack.

I'd also watch with 'current enel', as Enel went to the moon. We don't know what he's doing there, and it could be anything. He could return far more powerful, which I'm certainly hoping for. I want to see what he's capable of against someone who lacks Luffy's immunity.
