Two or three arrancar with Segunda Etapa could probably wipe out most of canon Soul Society, and so far the Captains we've made, Death included, are actually quite the downgrade in power from what we're used to seeing in the canon.
But now the Arrancar with Segunda Etapa outnumber the shinigami with bankai? That's not even remotely winnable even with the usual underdog status.
The only way that rationalizes in my mind is if for the purposes of this RP, Segunda Etapa is closer in power level to the usual bankai, but that hasn't been stated as far as I could see.
