Re: Taking Down Madara
I don't even really like Madara, but come on now. 1st of all, the edos you've mentioned can't control themselves. Only Madara and Itachi can. So they're only in Orochimaru and Kabuto's arsenal. Even if they were in control, perfect susanoo+mokuton+rinnegan>>edo Third Raikage and Minato. They're fast, but it doesn't mean they could do much to a guy who toyed with five kage, and has toyed with everyone in this war for the most part.
Itachi made have the Yata mirror, but that isn't going to protect him against perfect susanoo which cut down mountains. Even if it could, (which it can't), Madara could merely use mokuton and drag Itachi out of susanoo and seal him.
Orochimaru is debatable, technically, Hashirama broke out so he only has Tobirama, Hiruzen, and Minato. All very powerful, but I would still Say edo Madara could take it. Mokuton, rinnegan, and perfect susanoo are hard to deal with.
Kabuto and his army, heck yeah. They'd win.
Your Minato vs Madara argument:
For Minato to fight against edo Madara and his ftg kunai to be useful, he's going to need prep time that can teleport him far away from the battlefield. Madara's meteor alone would destroy all of the Kunai on the field. So Minato would need a lot more Kunai then he normally uses. If he could move without Orochimaru's consent that is. Unlike Madara, who was summoned and broke out of Kabuto's jutsu, Tho Oro gave him free will,....until Oro releases the jutsu or decides Minato is better off his puppet. So your argument falls under the "Orochimaru and the kages vs Madara".
