My Thoughts On Madara's Identity *Possible Spoilers*

[The Makage]

Okay, so in one of the most recent chapter of Naruto we've found out that the masked Madara....

Spoiler:

Might not actually be the real Madara because Muu summoned Madara to the battlefield and is now fighting against battalion 4

Anywho, everyone's had their ideas about who the masked Madara's identity could be, but I had a thought a couple of days ago as to a more subtle possibility as to who it could be...

Spoiler:

Could it be Shisui Uchiha...? Itachi once said that last time he'd seen Shisui, Danzo had taken one of his Sharingan, which would explain the one eyed mask he always wore. And another thing is, Kabuto and Orochimaru said they were never able to find the body and that it had "disappeared". What if there was no body to find, and Shisui's been alive all this time. Shisui had Mangekyou, he was a master of the Body Flicker technique, and after all this time "being dead" he could have found a way to turn it into that time-space jutsu that the masked Madara uses, and he has what's said to be one of the most powerful Genjutsu's in existance

Anyone think of this before? Cause it seems like it might be highly possible
