The most logical option would have been to start the first invasion with the weakest Stern Ritters, equal to the captains and lieutenants in power, and save the strongest Ritters for the second invasion that just started in the last chapter. That way the Wandenreich would gain the upper hand when the Gotei 13 expected Ritters equal to the captains in power, but were overpowered by much stronger Ritters.

There's a handful of Ritters I dunno where to put, strength-wise. Liltotto, Meninas, Candice and Giselle doesn't appear to be among the strongest, but neither did Yachiru, and she has proven to be extremely powerful despite her small and child-like appearance.

There's also a handful who appears to be based on previous characters:

Bazz-B --- Grimmjow - easily angered, medium strong?

Mask De Masculine --- Yammy - great physical power, average intellect

Äs Nödt --- Ulquiorra? - appears to be very strong and intelligent

I get a "Ulquiorra and Yammy" feeling of Äs Nödt and Mask De Masculine. The sequence where Mask said he thought only captains coud use Bankai and Äs berated him for not reading the Daten close enough, reminds me of the sequence where Ulquiorra hits Yammy in the stomach after he failed to realize who and how powerful Kisuke and Yoruichi were.
