Yeah they definitely will suffice! Models on the site aren't required to be rigged (with the exception of a few obvious games) but especially when you can't get them. If you do figure out how to rip their armatures properly later on, you'll have the option to revise your submissions with the updated models.

While the models of the characters can be ripped with their skeletons intact, The vertex weights are all jumbled in the models i dumped from Bluestacks' cache, Which makes all the models i dumped from it unusable in their current state aside from their "Chibi" models.
The character models in this game are almost identical to Mario Kart 8 but lower poly with smaller textures, As well as the additional "Chibi" models for when a character loses a health point, Once i can figure out how to correct the rigging i'd be happy to share them with everyone else (Maybe the unrigged models will suffice untill then?)

I have the models and textures for the other characters from dumping them out of Bluestacks' cache, And i am able to extract the textures and models, The only problem i'm having at the moment is that the rigging is screwy, Once i can solve that though i'll upload what i've got to this page.

Thank you, hope to see other char. as well
