Yeah, that won't happen, DB...
Mace and Dooku ARE leagues above Fisto and Maul. Otherwise, Fisto would have lasted much longer than he did against Palpatine, and Maul wouldn't have been killed by Kenobi at all. And he was still better than Kenobi anyways...
I say the Jedi take this. Kit Fisto would out-lightsaber Maul in a straight fight, while Dooku and Mace fight it out. Dooku would defeat Mace after some time, but having Fisto and Mace on him might not give him that chance.
Then again, Windu and Dooku could take the 'knock out the lesser fools' and take down Maul and Fisto with ease, then go at it. In that instance, the Sith win.
