Let we try to order the informations and think rationally. The War Powers, as they are very powerful, were all contacted by Yhwach, and very early. In facts, Ichigo was attacked at the very beginning of the arc, while Zaraki was beaten from Yhwach, while Aizen had a met with him. The other two members of this list should be uncontactable for the Silbern 'till now, or they went in battle later.

Reasoning so, Urahara could be a good option: he wasn't reached by any enemy during his time in the Human World 'cause it would be a waste of Sternritter, and remember that the Silbern attacked the Soul Society only when BOTH Ichigo and Urahara were in Hueco Mundo. This wasn't said in the arc, but it's obvious: who is the only shinigami who has a Garganta in the Human World, near to Ichigo? Urahara is, anyway, a very powerful combatant, master in all fighting arts (hakuda, kido, sword,...). His bankai is "too powerful to be used", and his inventions helped a lot the Soul Society.

For the fifth member we can choose in a small list, as many people can be. I wrote the list thinking so: as this is the last arc ever, all characters must show on. So the final Special War Power must be someone who appeard just a few, enough to create mystery around him/her but not enough to be an important character. This totally EXCLUDES Chad and Orihime: they have fought since the very beginning, and we know a lot about their powers through the Fullbringers Arc (Chad) and the Arrancar Arc (Inoue). More about Orihime can be found out in the powers of Hacigen, so she probably isn't in the list. I thought a thing more like Yoruichi: she was a captain, so she is quite powerful. She didn't appear a lot, and when she did, they weren't "busy" appearences. She never shown even the shape of his Zanpakuto: it can be an important thing! And remember that she is the first Shunpo-master in Soul Society.

Another good character might be Mayuri, for his strenght and inventions. I believe he hide something under his Bankai, and over all i think he can become similar to a god through zombies. Why am i saying this? 'cause i noticed that some Espada didn't disappear, but simply lie on the ground: Stark (who fell from the sky), Nnoitra (who stayed on the sand after the battle with Zaraki), Grimmjow (who were even alive during his final appearance), Yammi (really, i don't remember if he has died or not...). Kurotsuchi released the zombies of Privaròn Espada and Fracciòn, so why can't he use Espada?

In the list there is even Tessai, the "lieutenant" of Urahara in the Human World. He were a captain, and he knows forbidden kidos. And he really didn't do anything in the whole manga. It's strange, isn't it? After them, the member could be both Kyoraku and Ukitake, with the second more probably. This 'cause Kyoraku in this war is yet active, with the "battle" with Hascwalth (i don't even know how to write it... :D). Ukitake is nearly "escaped" in a strange temple: i think it is so 'cause he is preparing as well for his Bankai, which could be the reason of his illness.

My list has ended here, but there are other characters who have to appear, anyway. Like some of Fullbringers: we saw Tsukishima and at least another of 'em going around in Soul Society. Will they appeare? And where has Yachiru gone? And Isane? Certainly this is not the right place to talk about these things, but the mystery remains.
