Seems pretty unlikely to me as Yhwach made it pretty clear he's out to completely annihilate Soul Society and every single Shinigami there is, I doubt very much he would associate with one of them, plus there is the added fact that noone in Soul Society seemed to realize that the Wandenreich even existed prior to the invasion. Lastly, given the current amount of firepower and knowledge they have as they have had a thousand years to prepare it seems unlikely that associating with him would be of any additional benefit.
