Elite upper Sternritters and regular normal Sternritters; I like the idea as well. I mean there are definitely tonnes of pretty unique powers that Kubo could use as epithets; I'd definitely recommend him to go check out the Superpower Wiki if I could. Such a useful wiki. Although the idea of unlettered Sternritter seems like a more likely idea to me...

But for me the problem would be how Kubo could introduce these new Sternritter (if they ever appear), especially now that Yhwach is in the Soul Palace. If they just randomly appeared, you'd start wondering where they were hiding in the last 100+ chapters.
