First of all, the information listed on Bleach Wiki, unless otherwise proven wrong in the future or changed by Kubo (which is often more likely), is finite; that is the end of that discussion.

Let me also entertain a few more things that User:Zf6hellion brought up, as well. While I do agree that there are some things that are wishy washy in Bleach, that still does not give you the right to bend the rules to your rule. Rules are established for them to be followed, possibly even expanded on, but not broken and twisted to fit one's own need. Unless you are Tite Kubo himself, then you have no right to determine what rules you can make for yourself or how you can break them, even if Bleach is coherent storyline or not. If you have not noticed Naruto's Masashi Kishimoto has a knack for breaking his own rules, as well as many other manga artists, so it should not come as a shock Kubo does the same.
 * For starters, Kaname Tousen did indeed have a shikai and bankai but, if you watched the episode where he fought Shuhei and Sajin, he did not use either release a single time; he only used his sealed form and his Resurrección. Using a little common sense, it can go without saying that he could not use them (otherwise, would one not use such releases while fighting a captain and lieutenant in single combat).
 * Additionally, in his fight with, Uryu theorized that they share not only humanoid forms and Zanpakutou, but a common anatomy. He aimed for where a Shinigami's chain of fate would be and her powers were instantly lost.

I will offer this advice, though. If you really want to make a hybrid, make it so that one of the Shinigami's parents is an Arrancar. This will allow you some leway in granting them Arrancar powers, such as Visored mask-less cero, bala, pesquisa, etc.
