Well there is one thing to consider, Yachiru is the Lieutenant of the 11th division, one of the strongest divisions, and hangs around Kenpachi like all the time, who is considered to have one of the most powerful reiatsu's of any of the captains and she has never shown to be negatively affected by it in the least. If you consider even the 3rd seat (Ikakku) has a Bankai, there is a decent chance that she could have one as well, but we shall see. Anyway the point is is that she is pretty deceptively powerful even for a Lieutenant.
