Would Perfect Two Weapon Fighting work with Improved Whirlwind Attack?

I know about it letting you get additional attacks in a "Whirlwind" like attack. But would Duel Wielding let you get in extra attacks too? That would look either really cool, or really wierd.:smallconfused:

TWF attacks are still "based on your attack bonus"; I see no reason they can't be used with the feat.
