Aizen wanted Hogyoku to surpass limits of a shinigami, therefore implying he has mastered every way of shinigami martial arts, including zanjutsu, therefore that is invalid.

Zanjutsu is just Shinigami swordsmanship. It has nothing to do with utilizing Zanpakutō powers. Yes, Aizen did say that he wanted to surpass his limits as a Shinigami, but he also believed that he would have too much trouble against Yamamoto's Shikai with just his own Shikai. Yet he opted on using Wonderweiss instead of his Bankai(I wonder why that is). Honestly, I don't think Aizen was counting his unique powers when talking about surpassing Shinigami limits. He referred to the Shinigami limits as mastering the following forms of Shinigami combat: Zanjutsu, Hadō, Hohō, and Hakuda. I myself don't want to believe he doesn't have a Bankai, but you gotta admit that there's some decent evidence on him not having one. He probably didn't have a good bond with Kyōka Suigetsu. Probably as narcissistic as he is.
