It would make sense, but I highly doubt it. Why? Ulquiorra revealed that his second form wasn't known to even Aizen. Therefore, it wouldn't even be considered in their rankings.
Also, a Vasto Lorde is defined to be a hollow who has achieved human form. It was revealed quite a chapter back. Yes, Grimmjow's Fraccion was basically piled with Gillians-turned-Vasto Lorde (it was never confirmed, but you can tell by their human forms). The fact that they're all Vasto Lorde doesn't mean they're at the same power level, though. The only Gillian of the "current" Espadas was Aaronio Whateverthefuckhisnamewas.
EDIT: Actually, if I recall, there was one scene where the captains were commenting on how they were doomed if there were more than 5 Vasto Lorde in existance. The next scene showed a group of around 20-ish Vasto Lordes (according to Aizen's script).
Wow, I feel like such a Bleach nerd.
