If this theory would have been true, I would think they rather took Hueco Mundo because of Harribel. She was confirmed to be a Vasto Lorde, and she was ranked 3 places above Grimmjow as an Espada. I would think she has far greater power than him, unless the Espada were ranked after their level of reiryoku and not actual power.

Its anime/manga theory. Yamamoto is one of the most powerful dudes in Bleach yet Yhwach chose Kenny and Aizen, and Aizen even said Yamamoto was above his level. And think that Grimmjow is with Urahara now
