Garp and Sengoku stepping in gives the pirates 0 chance of winning. They were barely holding on with just the admirals, now step in two legendary fighters who fought with Roger?

Aside from Jozu, Marco, Vista, and WB none of the other WB pirates look anything above Vice Admiral. Crocodile is busy with Flamingo, Jinbei can arguably take out Moria and -possibly- help someone else after. Hancock will probably defect. Iva can take on Kuma. That leaves Mihawk with Vista. So basically you have Jinbei (if he beats Moria quickly), Hancock, Jozu, Marco, and WB against Garp, Sengoku, and three admirals.

Maybe if WB was in his prime he could give Sengoku and Garp a good go, but he will surely need help from someone (probably Jozu since he seems like a better fit against Garp's fist than Marco). I still don't see Marco, Hancock, and MAYBE Jinbei being able to take on the three admirals (although Hancock's haki will be interesting to see, as well as Jinbei's ability to use water against the Devil's Fruit). Then there is still marine's like Smoker who could be problematic. Who's left to save Ace on the pirates side? Squardo could play a role somewhere, surely.

Point is, at ABSOLUTE BEST the pirate are on-par with the marines. I think the Marines will win this one, but I still believe there will be a dramatic pendulum shift, even if temporary, to the pirates. Possibly with Garp doing something to save Ace, or Dragon showing up (which is very plausible with the opportunity at hand, as well as Luffy and Iva being present). Who knows, maybe Blackbeard will show up; off WB; then lay a quick smackdown on the marines before heading off, but I still don't see him making an appearance - but he is a nut and doesn't think very logically, so who knows.
You're forgetting the 20 PXs and Sentoumaru.
