@ Kuinra That theory makes the most sense except for one thing. Why didn't the captains/visoreds/lieutenants feel his spiritual pressure and recognize it? He was in FKT right after their own battle. Also how come he wasn't shown in the TBTP arc? He appears to have combat abilities around those of Aizen and Yama so there is no way he could have not been around by then. He is also probably going to end up being the Shiba uncle, which would make him older that Kaien, so again why wasn't he mentioned in the TPTP arc? He would fit into that time frame after the TPTP arc, except that it would be such an awkward fit. He is just to important and powerful of a character to to be shoved into a small 20 or 40 year time period without any previous mention of him.
